Physics - Electrostatics Question with Solution | TestHub

According to Gauss's law, the total electric flux through a closed surface is given by $$\varphi ={\oint }_s\vec{E}\cdot d\vec{s}=\frac{Q}{{\epsilon }_0}$$ where $Q$ is the total charge enclosed by the surface. The total charge enclosed by the given surface is $Q=+q-q=0.\therefore$ The total flux $\varphi =0$.
