A solid sphere and hollow sphere of same mass and radius rotate about their diameter with same rotational kinetic energy. If torques of equal magnitude are applied on them, ratio of their angular displacement before they are bought to rest.

View answer and explanation

Correct option: A

0.042361111

Option A (0.042361111) is correct as it represents the ratio of angular displacements calculated using the moments of inertia of a solid sphere and a hollow sphere and the work-energy theorem.
