The kinetic energy $K$ of a particle moving along a circle of radius $R$ depends on the distance covered $s$ as $K = a s^{2}$ . The centripetal force acting on the particle is

Options:

Answer:

Solution:

Kinetic energy $= \frac{1}{2} m v^{2} = K = a s^{2}$

or $m v^{2} = 2 a s^{2}$

Centripetal force = $\frac{m v^{2}}{R} = \frac{2 a s^{2}}{R}$
