Physics - Electrostatics Question with Solution | TestHub

When a sphere encloses a charged dipole,Here, $q=\pm 3\times 10^{-6}\mathrm{C}$ Thus, according to Gauss's law, the net electric flux across the closed surface is equal to the net charge enclosed by it divided by ${\epsilon }_0$, i.e. ${\varphi }_{\mathrm{E}}=\frac{{\mathrm{q}}_{\mathrm{in}}}{{\epsilon }_0}=\frac{+3\times 10^{-6}-3\times 10^{-6}}{{\epsilon }_0}=0$ Hence, electric flux across the sphere is zero.
