A body of mass m moving around a circle of radius r with a uniform speed v experiences a centripetal force F. The work done by the centripetal force on it is
Fv
zero
Fmr
\(\frac{Fr}{m}\)
Correct answer is B
Work is done whenever the given conditions are satisfied. (ii) there is a displacement of the body caused by the applied force along the direction of the applied force. No displacement takes place in this case. So, work done by a centripetal force is always zero.
The work done by centripetal force in the case of a uniform circular motion is 0 joules.
