A hollow spherical shell of radius $r$ has a uniform charge density $\sigma$. It is kept in a cube of edge $3 r$ such that the centres of the cube and the shell coincide. Then the electric flux coming out of one face of a cube is ( $\varepsilon_0=$ permittivity of free space)

$\frac{\pi r^2 \sigma}{\varepsilon_0}$

$\frac{5 \varepsilon_0}{2 \pi r^2 \sigma}$

$\frac{\pi r^2 \sigma}{6 \varepsilon_0}$

$\frac{2 \pi r^2 \sigma}{3 \varepsilon_0}$
