Question

When a body moves under a effect of of a centripetal force , how much work is done by the centripetal force?

Answer 1

When a body is moving in a circular motion a force starts acting on it which is towards the centre of circle called centripetal force and the force is always perpendicular at every instant of time .hence the angle made between force and displacement is 90⁰ hence the work done is zero at every point of time.
