A diver in a swimming pool bends his head before diving. It

A

increases his linear velocity

B

decreases his angular velocity

C

increases his moments of inertia

D

decreases his moment of inertia

Text Solution

Verified by Experts

The correct Answer is:
D
When a diver bends his head, radius of gyration R decreases.
Moment of inertia `I=MR^(2)`
Since R decreases, moment of inertia also decreases.
