Question

In case of circular motion of a body, if tangential force also acts on the body in addition to centripetal force, then work done: (A) by tangential force is zero by work done by centripetal force is not zero. (B) by centripetal force is zero but work done by tangential force is not zero (C) by both the forces is positive (D) by both the forces is zero

Since there is no displacement along radius vector hence work done is zero by centripetal force, but for tangential force there is displacement =2π R, so work done is not zero.

by centripetal force is zero but work done by tangential force is not zero

by both the forces is positive

by both the forces is zero

Since there is no displacement along radius vector hence work done is zero by centripetal force, but for tangential force there is displacement $= 2 π R,$ so work done is not zero.
