A body moves with a speed of `2 pi m s^(-1)` in a cirular path of radius 1 m , then the time taken to compete one revolution is ________.

A

1

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
A
Speed = ` ("distance")/("time") `
` " Time" = (" distance") /("speed") = (2pi xx r)/(2pi) = (2 pi xx 1)/ (2pi) 1 s`
