Assertion : It is difficult to move a cycle along the road with its brakes on. Reason : Sliding friction is greater than rolling friction.

Options

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

When brakes are on, there is no rolling of the wheels and the wheels slide. The sliding friction is greater than the rolling friction. Thus it is difficult to move a cycle along the road with its breaks on.
