Assertion: a static electric field can be written as the gradient of a scalar potential. Reason: the curl of a gradient vanishes identically.

  • A.both the assertion and the reason are true and the reason explains the assertion
  • B.both the assertion and the reason are true but the reason does not explain the assertion
  • C.the assertion is true but the reason given for it is false
  • D.the assertion is false although the reason offered is a true statement in itself

Answer: A

The static field is irrotational, and the identity guarantees that any gradient is irrotational, so the representation is consistent. It is the vanishing curl of the static field that makes a scalar potential possible at all.
