A square loop of sides $\displaystyle a=1 \mathrm{~m}$ is held normally in front of a point charge $\displaystyle \mathrm{q}=1 \mathrm{C}$. The flux of the electric field through the shaded region is $\displaystyle \frac{5}{\mathrm{p}} \times \frac{1}{\varepsilon_0} \frac{\mathrm{Nm}^2}{\mathrm{C}}$, where the value of p is $\displaystyle \_\_\_\_$.
