A body having its centre of mass at the origin has three of its particles at (a,0,0), (0,a,0), (0,0,a). The moments of inertia of the body about the X and Y axes are 0.20 kg—m2 each. The moment of inertia about the Z-axis
(a) is 0.20 kg-m2
(b) is 0.40 kg-m2
(c) is 0.20-√2 kg-m2
(d) cannot be deduced with this information.
