Assertion: A solid sphere and a hollow sphere are rolling on ground with same total kinetic energies. If translational kinetic energy of solid sphere is

K

, then translational kinetic energy of hollow sphere should be greater than

K

.

Reason: In case of hollow sphere rotational kinetic energy is less than its translational kinetic energy.

View answer and explanation

Correct option: D

If Assertion is false but the Reason is true

Option D (If Assertion is false but the Reason is true) is correct because the assertion is false, and the reason is true. The hollow sphere's translational kinetic energy is less than K.
