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 $\displaystyle \omega$ about their own symmetry axes. The amounts of work (W) required to bring them to rest, would satisfy the relation
Official answer
From NTA’s final answer key for this paper.
