A stone of mass M tied at the end of a string, is moving in a circular of radius R, with a constant angular velocity `omega`. The work done on the stone, in any half circle I s

A

`pi MR^(2)omega^(2)`

B

`2 MR^(2) omega^(2)`

C

`MR^(2)omega^(2)`

D

0

Text Solution

Verified by Experts

The correct Answer is:
D
`(` Easy `)` Since there is no change in kinetic energy of stone, the total work doen on stone in any duration is zero.
