Final Answer : 20uC/£
where £ ispermitivity in given medium.
By Gauss's Law,
The Electric field due to any closed surface is equal to the net charge enclosed inside the surface divided by permitivity in given medium.
So, here flux is independent of radius of Gaussian surface.
It remains same on changing the radius.
Therefore, flux will be 1/£ times net charge enclosed inside.
