Physics System of Particles Rotational Motion Statement Based MCQ (Single Correct)

Statement I: A wheel moving down a perfectly frictionless inclined plane will undergo slipping (not rolling motion).

Statement II: For perfect rolling motion, work done against friction is zero.
In the light of the above statements, choose the most appropriate answer from the options given below.

Both Statement I and Statement II are incorrect.

Statement I is correct but Statement II is incorrect.
