Assertion : Adding a scalar to a vector of the same dimensions is a meaningful algebraic operation. Reason : The displacement can be added with distance.

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

Scalar and vector are quantities of different nature. We can add only those quantities which have same nature and units.
