Assertion : Centripetal force does no work. Reason : Force and displacement are perpendicular to each other.

Options

  1. AIf both AA and 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 Assertion is false but Reason is true.

Correct answer

A. If both AA and and Reason are true and Reason is the correct explanation of Assertion.

Step-by-step solution

Since centripetal force is perpendicular to the displacement of the body, work done is zero as W=\vec{F} \cdot \vec{d}=F d \cos \theta
