Physics System of Particles Rotational Motion Assertion & Reason MCQ (Single Correct)

In this question, a statement of assertion is followed by a statement of reason . Mark the correct choice as:

Assertion: A sphere cannot roll on a smooth inclined surface.
Reason: For a smooth inclined surface force of friction is equal to zero.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If assertion is false but reason is true.

Text Solution
