(A): Value of radius of gyration of a body depends on axis of rotation.
(R): Radius of gyration is root mean square distance of particle of the body from the axis of rotation.
(R): Radius of gyration is root mean square distance of particle of the body from the axis of rotation.
View answer and explanation
Correct option: A
Both (A) and (R) are true and (R) is the correct explanation of (A)
Option A (Both (A) and (R) are true and (R) is the correct explanation of (A)) is correct because the radius of gyration depends on the axis of rotation, and the reason correctly defines the radius of gyration.
