  • Question

  • Assertion (A): ?0 has the dimensions of farad per meter.

    Reason (R): D = ?0?r E.


  • Options
  • A. Both A and R are true and R is correct explanation of A
  • B. Both A and R are true but R is not correct explanation of A
  • C. A is true but R is false
  • D. A is false but R is true

  • Correct Answer
  • Both A and R are true but R is not correct explanation of A 

    Explanation
    The dimensions of ?0 can be derived from the expression D = ?0?r E.
