Electric Flux & Gauss's Law

The electric flux entering and leaving an enclosed surface are $\Phi_1$ and $\Phi_2$ respectively. The electric charge inside the surface will be ( $\varepsilon_0$ = permittivity of vacuum)

Show answer and solution

Answer: (d)

Net outward flux $= \Phi_2 - \Phi_1$ (leaving minus entering).
Gauss's law: $\Phi_2 - \Phi_1 = \dfrac{q}{\varepsilon_0} \Rightarrow q = \varepsilon_0(\Phi_2 - \Phi_1)$
So the answer is (d).
