Three objects, A (a solid sphere), B (a thin circular disk) and C (a circular ring), each have the same mass M and radius R. They all spin with the same angular speed ω about their own symmetry axes. The amounts of work (W) required to bring them to rest, would satisfy the relation:-
1
WC > WB > WA
2
WA > WB > WC
3
WB > WA > WC
4
WA > WC > WB
