Value of radius of gyration of a body depends on axis of rotation.
Radius of gyration is root mean square distance of particle of the body from the axis of rotation.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
a
Radius of gyration of a body about a given axis is equal to
K = `sqrt(r_1^(2) + r_2^(2) + …..r_n^(2)) / n`.
It thus depends upon shape and size of the body, position and configuration of the axis of rotation and also on distribution of mass of body w.r.t the axis of rotation.
