When a sphere rolls down an inclined plane, then identity the correct statement related to the work done by friction force

View answer and explanation

Correct option: C

The net work done by friction is zero

Option C (The net work done by friction is zero) is correct because while friction does negative work in the translational sense, it does positive work in the rotational sense, resulting in zero net work.
