A body of mass

1 \mathrm{~kg}

is rotated in a horizontal circle of radius

1 \mathrm{~m}

and moves with velocity

2 \mathrm{~m} / \mathrm{sec}

. The work done in 10 revolutions is

View answer and explanation

Correct option: D

Zero

The correct answer is D (Zero) because the work done in uniform circular motion is zero as the force is always perpendicular to the displacement.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in

\mathrm{m}{\mathrm{s}^{ - 1}}

\mathrm{\vec F} = - K\left( {y\hat i + x\hat j} \right)

(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x-axis to the point (a,0) and then parallel to the y-axis to the (a,a). The total work done by the force
