A body of mass 10kg performs motion along a circle of radius 5m with speed of `10ms^(-1)`. Work done during one revolution is ………….J.

A

`2000pi`

B

`1000pi`

C

`500pi`

D

zero

Text Solution

Verified by Experts

Here the object performs uniform circular motion. The angle between the centripetal force acting on it and the direction of displacement at any point on the circular path is `90^(@)`. So `W=F_(1)xxs=0xxs=0`
Where. `F_(1)` = Effective force along direction of displacement
