A person is standing on a rotating table with metal spheres in his hands. If he withdraws his hands to his chest, then the effect on his angular velocity will be.

A

increase

B

decrease

C

remain same

D

can't say

Text Solution

Verified by Experts

The correct Answer is:
A
When the person withdraws his hands to his chest, his moment of inertia decreases. No external torque is acting on the system. So to conserve angular momentum, the angular velocity increases.
