The work done by a centripetal force
increases by decreasing the radius of the circle
decreases by increasing the radius of the circle
increases by increasing the mass of the body
is always zero
Thus, the work done by a centripetal force is always zero.
Hence, option D is correct.
Work done by centripetal force is zero.
When a body moves under a effect of of a centripetal force , how much work is done by the centripetal force?
