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

    Statement I: A body moving in a circular path is acted upon by the centripetal force. Statement II: Centripetal force acting on the body is doing work to keep it rotating in the circular path.

    A body is undergoing non-uniform circular motion. Work done by radial force on the body is

    Statement -1 : The work done by induced electric field along a closed path is zero. Statement -2 : The induced electric field is non - conservative.

    In case of circular motion a body, if tangential force also acts on the body in addition to centripetal force, then work done:
