Answer:

Radius of gyration of a rigid body about an axis of rotation is the distance between the axis of rotation and a point at which the whole mass of the body can be supposed to be concentrated b/so that its moment of inertia would be the same with the actual distribution of mass. K = . Its S I unit is m and CGS unit is cm.

Answer 2

Answer:

it is measured in m

dimensional formula is M0L1T0
