Electric Flux & Gauss's Law

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A: If an electric dipole of dipole moment 30×10−5 C m30 \times 10^{-5}\text{ C m} is enclosed by a closed surface, the net flux coming out of the surface will be zero.

Reason R: Electric dipole consists of two equal and opposite charges.

In the light of the above statements, choose the correct answer from the options given below.

Show answer and solution

Answer: (d)

  1. A dipole has charges +q+q and −q-q, so net enclosed charge is zero.
  2. By Gauss's law the net flux is zero, so A is true.
  3. R is true and is exactly why the enclosed charge is zero.
  4. So the answer is (d).
