Very Short Answer Type Questions<\/span><\/p>\n

Question 1.
\nWrite the equation for the horizontal range covered by a projectile and specify when it will be maximum. [TS May ’16]
\nAnswer:
\nRange of a projectile (R) = \\(\\frac{u^2 \\sin 2 \\theta}{g}\\)
\nWhen \u03b8 = 45\u00b0 Range is maximum.
\nMaximum Range (Rmax<\/sub>) = \\(\\frac{u^2}{g}\\)<\/p>\n

Question 2.
\nThe vertical component of a vector is equal to its horizontal component. What is the angle made by the vector with x-axis? [AP Mar. ’19; TS May ’18]
\nAnswer:
\nLet R be a vector.
\nVertical component = R sin \u03b8;
\nHorizontal component = R cos \u03b8
\n\u2234 R sin \u03b8 = R cos \u03b8.
\nSo sin \u03b8 = cos \u03b8 \u21d2 \u03b8 = 45\u00b0<\/p>\n

Question 3.
\nA vector V makes an angle \u03b8 with the horizontal. The vector is rotated through an angle \u03b1. Does this rotation change the vector V?
\nAnswer:
\nMagnitude of vector = V ;
\nLet initial angle with horizontal = \u03b8
\nAngle rotated = \u03b1
\nSo new angle with horizontal = \u03b8 + \u03b1
\nNow horizontal component,
\nV\u03b1<\/sub> = V cos (\u03b8 + \u03b1)
\nVertical component, Vy<\/sub> = V sin (\u03b8 + \u03b1)
\nMagnitude of vector, V = \\(\\sqrt{V^{2}_{x}+V^{2}_{y}}\\) = V
\nSo rotating the vector does not change its magnitude.<\/p>\n

Question 4.
\nTwo forces of magnitudes 3 units and 5 units act at 60\u00b0 with each other. What is the magnitude of their resultant? [AP Mar. 17. 15; May 17, 16]
\nAnswer:
\nGiven \\(\\overline{\\mathrm{P}}\\) = 3 units, \\(\\overline{\\mathrm{Q}}\\) = 5 units and \u03b8 = 60\u00b0
\n\"TS<\/p>\n

Question 5.
\nA = \\(\\overrightarrow{\\mathrm{i}}+\\overrightarrow{\\mathrm{j}}\\) What is the angle between the vector and x-axis? [TS Mar. ’17; AP Mar. ’14; May ’13]
\nAnswer:
\nGiven that, \\(\\overrightarrow{\\mathrm{A}}=\\overrightarrow{\\mathrm{i}}+\\overrightarrow{\\mathrm{j}}\\)
\n\"TS
\nIf ‘\u03b8’ is the angle made by the vector with x-axis then,

Question 6.
\nWhen two right angled vectors of magnitude 7 units and 24 units combine, what is the magnitude of their resultant? [AP Mar. 18, 16; May 18. 14]
\nAnswer:
\nGiven \\(\\overline{\\mathrm{P}}\\) = 7 units; \\(\\overline{\\mathrm{Q}}\\) = 24 units; 0 = 90\u00b0
\n\"TS<\/p>\n

Question 7.
\nIf \\(\\overline{\\mathrm{P}}\\) = 2i + 4j + 14k and \\(\\overline{\\mathrm{Q}}\\) = 4i + 4j + 10k, find the magnitude of \\(\\overline{\\mathrm{P}}+\\overline{\\mathrm{Q}}\\). [TS Mar. ’16, ’15]
\nAnswer:
\n\"TS<\/p>\n

Question 8.
\nCan a vector of magnitude zero have non-zero components?
\nAnswer:
\nA vector with zero magnitude cannot have non-zero components. Because magnitude of given vector \\(\\overline{\\mathrm{V}}\\) = \\(\\sqrt{V^{2}_{x}+V^{2}_{y}}\\) must be zero. This is possible only when V\u00b2x<\/sub> and V\u00b2y<\/sub> are zero.<\/p>\n

Question 9.
\nWhat is the acceleration of a projectile at the top of its trajectory? [TS Mar. ’19]
\nAnswer:
\nAt highest point acceleration, a = g. In projectile, motion acceleration will always acts towards centre of earth. It is irrespective of its position, whether it is at highest point or somewhere.<\/p>\n

\"TS<\/p>\n

Question 10.
\nCan two vectors of unequal magnitude add up to give the zero vector? Can three unequal vectors add up to give the zero vector?
\nAnswer:
\nNo. Two unequal vectors can never give zero vector by addition. But three unequal vectors when added may give zero vector.<\/p>\n

Short Answer Questions<\/span><\/p>\n

Question 1.
\nState parallelogram law of vectors. Derive an expression for the magnitude and direction of the resultant vector. [TS Mar. ’17, ’16, May ’17; AP Mar. ’14, ’13]
\nAnswer:
\nParallelogram Law :
\nIf two vectors are represented by the two adjacent sides of a parallelogram then the diagonal passing through the intersection of given vectors represents their resultant both in direction and magnitude.<\/p>\n

Proof :
\nLet \\(\\overline{\\mathrm{P}}\\) and \\(\\overline{\\mathrm{Q}}\\) be two adjacent vectors ‘\u03b8’ be angle between them. Construct a parallelogram OACB as shown in figure. Extend the line OA and draw a normal D from C. The diagonal OC = the resultant \\(\\overline{\\mathrm{R}}\\) both in direction and magnitude.

\nAngle of resultant with adjacent side ‘\u03b1’
\n\"TS<\/p>\n

Question 2.
\nWhat is relative motion? Explain it.
\nAnswer:
\nRelative velocity is the velocity of a body with respect to another moving body.<\/p>\n

Relative velocity in two dimensional motion :
\nLet two bodies A and B are moving with velocities \\(\\overrightarrow{\\mathrm{V}}_A\\) and \\(\\overrightarrow{\\mathrm{V}}_B\\) then relative velocity of Aw.r.t B is \\(\\overrightarrow{\\mathrm{V}}_{AB}=\\overrightarrow{\\mathrm{V}}_{A}+\\overrightarrow{\\mathrm{V}}_{B}\\)
\nRelative velocity of B w.r.t. A is
\n\\(\\overrightarrow{\\mathrm{V}}_{BA}=\\overrightarrow{\\mathrm{V}}_{B}-\\overrightarrow{\\mathrm{V}}_{A}\\)
\n\"TS
\nProcedure to find resultant :
\nTo find rela-tive velocity in two dimensional motion use vectorial subtraction of VA<\/sub> or VB<\/sub>. Generally to find relative velocity one vector \\(\\overrightarrow{\\mathrm{V}}_A\\) or \\(\\overrightarrow{\\mathrm{V}}_B\\) is reversed (as the case may be) and parallelogram is constructed. Now resultant of that parallelogram is equal to \\(\\overrightarrow{\\mathrm{V}}_A-\\overrightarrow{\\mathrm{V}}_B\\) or \\(\\overrightarrow{\\mathrm{V}}_B-\\overrightarrow{\\mathrm{V}}_A\\) (8\u00b0 one vector is reversed VA<\/sub> is taken as –\\(\\overrightarrow{\\mathrm{V}}_A\\) or \\(\\overrightarrow{\\mathrm{V}}_B\\) is taken as –\\(\\overrightarrow{\\mathrm{V}}_B\\))
\nIn figure relative velocity of B w.r.t A is VBA<\/sub> =VR<\/sub> = VB<\/sub> – VA<\/sub>.<\/p>\n

Question 3.
\nShow that a boat must move at an angle with respect to river water in order to cross the river in minimum time.
\nAnswer:
\nMotion of a boat in a river :
\nLet a boat can travel with a speed of VbE<\/sub> in still water w.r. to earth. It is used to cross a river which flows with a speed of VWE<\/sub> with respect to earth. Let width of river is W.
\n\"TS<\/p>\n

We can cross the river in two different ways.
\n1) in shortest path 2) in shortest time.<\/p>\n

To cross the river in shortest time :
\n\"TS<\/p>\n

To cross the river in shortest time boat must be rowed along the width of river i.e., boat must be rowed perpendicular to the bank or 90\u00b0 with the flow of water. Because width of river is the shortest distance. So velocity must be taken in that direction to obtain shortest time. In this case VbE<\/sub> and VWE<\/sub> are perpendicular and boat will travel along AC. The distance BC is called drift. So to cross the river in shortest time angle with flow of water = 90\u00b0.<\/p>\n

Question 4.
\nDefine unit vector, null vector and position vector. [AP June ’15]
\nAnswer:
\nUnit vector :
\nA vector whose magnitude is one unit is called unit vector.<\/p>\n

Let a is \\(\\overline{\\mathrm{a}}\\) given vector then unit vector
\n\"TS<\/p>\n

Null vector :
\nA vector whose magnitude is zero is called null vector. But it has direction.<\/p>\n

For a null vector the origin and terminal point are same.
\nEx : Let \\(\\overline{\\mathrm{A}}\\times\\overline{\\mathrm{B}}=\\overline{\\mathrm{0}}\\) . Here magnitude of \\(\\overline{\\mathrm{A}}\\times\\overline{\\mathrm{B}}=\\overline{\\mathrm{0}}\\) . But still it has direction perpendicular to the plane of \\(\\overline{\\mathrm{A}}\\) and \\(\\overline{\\mathrm{B}}\\).<\/p>\n

Position vector :
\nAny vector in space can be represented by the linear combination
\n\"TS<\/p>\n

Question 5.
\nIf |\\(\\overrightarrow{\\mathrm{a}}+\\overrightarrow{\\mathrm{b}}\\)| = |\\(\\overrightarrow{\\mathrm{a}}-\\overrightarrow{\\mathrm{b}}\\)|, prove that the angle between \\(\\overrightarrow{\\mathrm{a}}\\) and \\(\\overrightarrow{\\mathrm{b}}\\) is 90\u00b0. [TS Mar., May ’18]
\nAnswer:
\nLet \\(\\overrightarrow{\\mathrm{a}}\\), \\(\\overrightarrow{\\mathrm{b}}\\) are the two vectors.
\nSum of vectors
\n\"TS
\nby squaring on both sides,
\na\u00b2 + b\u00b2 + 2ab cos \u03b8 = a\u00b2 + b\u00b2 – 2ab cos \u03b8
\n\u2234 4 ab cos \u03b8 = 0 or \u03b8 = 90\u00b0
\n\"TS<\/p>\n

Question 6.
\nShow that the trajectory of an object thrown at certain angle with the horizontal is a parabola. [AP Mar. ’18, ’17. ’16. ’15, May ’18, ’17, ’14. ’13; June ’15; TS Mar. ’18, ’15, May ’16, June ’15]
\nAnswer:
\nProjectile :
\nA body thrown into the air same angle with the horizontal, (other tan 90\u00b0) its motion under the influence of gravity is called projectile. The path followed by it is called trajectory.<\/p>\n

Let a body is projected from point O, with velocity ‘u\u2019 at an angle \u03b8 with horizontal. The velocity u\u2019 can be resolved into two rectangular components ux<\/sub> and uy<\/sub> along x-axis and y-axis.
\nux<\/sub> = u cos \u03b8 and uy<\/sub> = u sin \u03b8<\/p>\n

After time t, Horizontal distance travelled x = u cos \u03b8 . t ……….. (1)
\n\"TS
\nAfter a time t’ sec; vertical displacement
\n\"TS
\nThe above equation represents “parabola”. Hence the path of a projectile is a parabola.<\/p>\n

Question 7.
\nExplain the terms the average velocity and instantaneous velocity. When are they equal ?
\nAnswer:
\nAverage velocity :
\nIt is the ratio of total displacement to total time taken.
\n\"TS<\/p>\n

Average velocity is independent of path followed by the particle. It just deals with initial and final positions of the body.<\/p>\n

Instantaneous velocity :
\nVelocity of a body at any particular instant of time is defined as instantaneous velocity.<\/p>\n

\"TS
\nas instantaneous velocity.
\nFor a body moving with uniform velocity its average velocity = Instantaneous velocity.<\/p>\n

Question 8.
\nShow that the maximum height and range
\n\"TS
\nrespectively where the terms have their regular meanings.
\nAnswer:
\nLet a body is projected with an initial velocity ‘u’ and with an angle \u03b8 to the horizontal. Initial velocity along x direction, ux<\/sub> = u cos \u03b8 Initial velocity along y direction, uy<\/sub> = u sin \u03b8<\/p>\n

Horizontal Range :
\nIt is the distance covered by projectile along the horizontal between the point of projection to the point on ground, where the projectile returns again.<\/p>\n

It is denoted by R. The horizontal distance covered by the projectile in the to time of flight is called horizontal range. Therefore, R = u cos \u03b8 \u00d7 t.
\n\"TS<\/p>\n

Angle of projection for maximum range:
\nFor a given velocity of projection, the horizontal range will be maximum, when sin 2\u03b8 = 1.
\n\u2234 Angle of projection for maximum range is 2\u03b8 = 90\u00b0 or \u03b8 = 45\u00b0
\n\u2234 Rmax<\/sub> = \\(\\frac{u^2}{g}\\)<\/p>\n

Maximum height :
\nThe vertical distance covered by the projectile until its vertical component becomes zero.
\n\"TS<\/p>\n

Question 9.
\nIf the trajectory of a body is parabolic in one reference frame, can it be parabolic in another reference frame that moves at constant velocity with respect to the first reference frame? If the trajectory can be other than parabolic, what else can it be?
\nAnswer:
\nYes. According to Newton’s first law, a body at rest or a body moving with uniform velocity are treated as same. Both of them belong to inertial frame of reference.<\/p>\n

If a frame (say 1) is moving with uniform velocity with respect to other, then that second frame must be at rest or it maintains a constant velocity w.r.t the first. So both frames are inertial frames. So if trajectory of a body in one frame is a parabola, then trajectory of that body in another frame is also a parabola.<\/p>\n

Question 10.
\nA force 2i + j – k newton acts on a body which is initially at rest. At the end of 20 seconds the velocity of the body is 4i + 2j – 2k ms-1. What is the mass of the body? [AP May ’16]
\nAnswer:
\nForce, F = 2i + j – k
\ntime, t = 20
\nInitial velocity, u = 0
\nFinal velocity, v = 4i + 2j – 2k = 2(2i + j – k)
