In the following question, a statement of Assertion is followed by a statement of Reason. Assertion: When a body moves along a circular path, the work done by a centripetal force is zero. Reason: The centripetal force is utilised in moving the body along the circular path and hence the work is done. Choose one of the following statements is correct?

What is the work done by centripetal force ?

What is the work done by centripetal force?/

When a body is whirled in a circle, the work done on it is

When a body moves in a circular path, no work is done by the force since,

When a body moves in a circular path, no work is done by the force since,

Derive an expression for centripetal force acting on a body moving in a circular path. Is any work done by centripetal force ? Explain.
