A closed cylindrica tube containing some water (not filling the entire tube) lies in a horizontal plane. If the tueb is rotated about a perpendicular bisector, the moment of inertia of water about the axis

A

increases

B

decreases

C

remains constant

D

increases if the rotation is clockwise.

Text Solution

Verified by Experts

As the tube rotates, water moves towards the ends of tube, hence the moment of inertia increases.
