Answer #1

Radius of gyration of a body about an axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated.Therefore, I=MK^2, Now using the formula of torque =I × angular acceleration, torque has besn calculated
