Problem

Which of the following expressions gives the moment of inertia

I

of a rigid body about an axis that is parallel to and a distance

d

away from an axis through the centre of mass, if the moment of inertia about the centre-of-mass axis is

I_{\mathrm{CM}}

and the mass of the body is

M

? a)

I = I_{\mathrm{CM}} - Md^{2}

I = I_{\mathrm{CM}} + \dfrac{1}{2}Md^{2}

I = Md^{2}

I = I_{\mathrm{CM}} + Md^{2}
