Assertion: On a banked curved track, vertical component of normal reaction provides the necessary centripetal force. Reason : Centripetal force is not always required for turning.

Options

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

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Centripetal force is provided by the horizontal component of normal reaction. Vertical component balances the weight of the vehicle. Centripetal force is required for turning. Hence, both, assertion and reason are false.
