Rotational MotionHard

Question

A rigid body of mass m rotates with angular velocity w about an axis at a distance d from the centre of mass G. The radius of gyration about a parallel axis through G is K. The kinetic energy of rotation of the body is : -

Options

A.mk2ω2
B.md2ω2
C.m(d2 + k22
D.m(d + k)2ω2

Solution

I′ = MK2 + Md2 (∵ I = Icm + md2)
