Choose the wrong statement.

A

The centre of mass of a uniform circular ring is at its geometric centre

B

Moment of inertia is scalar quantity

C

Radius of gyration is a vector quantity

D

Force in translational motion is analogous to torque in rotational motion

Text Solution

Verified by Experts

The correct Answer is:
B
Moment of inertia is not a scalar quantity so the option (b) is wrong.
