The radius of gyration of a body depends upon

A

mass of the body

B

nature of distribution of mass

C

axis of rotation

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B, C
We know that `K=sqrt(I/M),IpropM` hence radius of gyration does not depends upon mass of the body. Further `I` depennds upon distribution of mass of body and also on the axis of rotation. Hence `K` also depends upon these factors.
