Show answer and solution
Answer: (A)
As per gauss theorem,
$\begin{aligned}& \phi=\frac{\mathrm{q}_{\text {in }}}{\epsilon_0}=\frac{\mathrm{q}+(-2 \mathrm{q})+5 \mathrm{q}}{\epsilon_0} \\
& \frac{4 \mathrm{q}}{\epsilon_0}\end{aligned}$
$\begin{aligned}& \phi=\frac{\mathrm{q}_{\text {in }}}{\epsilon_0}=\frac{\mathrm{q}+(-2 \mathrm{q})+5 \mathrm{q}}{\epsilon_0} \\
& \frac{4 \mathrm{q}}{\epsilon_0}\end{aligned}$
