Four small objects each of mass m are fixed at the corners of a rectangular wire-frame of negligible mass and of sides a and b (a > b) . If the wire frame is now rotated about an axis passing along the side of length then the moment of inertia of the system for this axis of rotation is:

Four small objects each of mass m are fixed at the corners of a rectangular wire-frame of negligible mass and of sides a and b (a gt b) . If the wire frame is now rotated about an axis passing along the side of length b, then the amount of inertia of the system for this axis of rotation is
