Answer (3)
Sol. \phi_{\text {Total }}=\frac{\mathbf{q}_{\text {enclosed }}}{\varepsilon_{0}}

Because dipoles have equal and opposing charges, there will be no net charge inside the sphere.

\left(q_{\text {enolosed }}=0\right)
\begin{aligned} \phi_{\text {Total }} &=\frac{0}{\varepsilon_{0}} \\ &=0 \end{aligned}
