A body is moving along a circular path. How much work is done by the centripetal force? Or             Why is the work done by centripetal force zero?                                              

Answer:

                For a body moving along a circular path, the centripetal force acts along the radius while the displacement is tangential i.e., \[\theta ={{90}^{\circ }},\], therefore\[W=Fs\cos {{90}^{\circ }}=0\].
