AIIMS 2010 Physics Rolling Motion Assertion Reason Question
Assertion: A wheel moving down a perfectly frictionless inclined plane will undergo slipping (not rolling motion). Reason: For perfect rolling motion, work done against friction is zero.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false.
Both Assertion and Reason are false.
Correct Answer
Detailed Explanation
Rolling occurs only on account of friction which is a tangential force capable of providing torque when the inclined plane is perfectly smooth.
