The masses are Q=0.400 kg, R=0.700 kg, and S=0.800 kg. Calculate the moment of inertia (of the 3 masses) with respect to an axis perpendicular to the xy plane and passing through x=0 and y=-2. [Since the masses are of small size, you can neglect the contribution due to moments of inertia about their centers of mass.]
Three small spherical masses are located in a plane at the positions shown below.
