A body of mass 100 g is rotating in a circular path of radius r with constant velocity. The work done in one complete revolution is
100 rJ
(r100)J
(100r)J
Zero
Work done in circular motion is always zero.
A body of mass 10 kg is moving on a circular track of radius 15 m. What is work done on it in one complete revolution? (Take g=10 ms−2)
