1.	A stone of mass M is tied at the end of a string, is moving in a circle of radius R, with a constant angular velocity `omega`. The total work done on the stone, in any half circle, is:A. `piMR^(2) omega^(2)`B. `2 MR^(2) omega^(2)`C. `MR^(2) omega^(2)`D. 0
Answer» Correct Answer - D Since there is no change in kinetic energy of stone, the total work done on stone in any duration is zero.
