Electric Flux & Gauss's Law

A sphere encloses an electric dipole with charges ±3×10−6 C\pm 3 \times 10^{-6}\text{ C}. What is the total electric flux across the sphere?

Show answer and solution

Answer: (c)

  1. Net charge of a dipole =+q+(−q)=0= +q + (-q) = 0.
  2. Gauss's law: ϕ=qencε0=0\phi = \dfrac{q_{enc}}{\varepsilon_0} = 0.
  3. So the answer is (c) zero.
