The angular velocity of second's hand of a watch will be.

A

`(pi)/(60)` rad/sec

B

`(pi)/(30)` rad/sec

C

`pi` rad/sec

D

`30 pi` rad/sec

Text Solution

Verified by Experts

The correct Answer is:
B
We know that second.s hand completes its revolution `(2pi)` in 60 sec `therefore omega = (theta)/(t)=(2pi)/(60)=(pi)/(30)` rad/sec.
