A particle moves in a circular orbit of radius r under a central attractive force

F = - \frac{k}{r}

, k is constant. The time period of its motion is proportional to

View answer and explanation

Correct option: B

r

The correct answer is B (r) because the time period is proportional to the radius in this specific central force scenario.

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
