The shaft of a motor car rotates at constant angular frequancy of 3000 revolutions //min .The angle through which it has turned in one second in radians is

A

`100 pi`

B

`50 pi`

C

`25 pi`

D

`125 pi`

Text Solution

Verified by Experts

The correct Answer is:
A
`n_(1)=(3000)/(60)=50`
`theta =omega_(1)t=2pixxn_(1)t=2pixx50xx1`
`=1000pi`.
