Question

A body is moving in circular path . how much work is done by the centripetal force

Answer 1

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.

Answer 2

zero work is done as thebody comes to the same place after rotating and displacement being 0
