Electric Flux & Gauss's Law

If the electric flux entering and leaving an enclosed surface respectively is ϕ1\phi_1 and ϕ2,\phi_2, the electric charge inside the surface will be

Show answer and solution

Answer: (a)

  1. Net outward flux =ϕ2−ϕ1= \phi_2 - \phi_1.
  2. q=ε0(ϕ2−ϕ1)q = \varepsilon_0(\phi_2 - \phi_1)
  3. So the answer is (a).
