A point charge causes an electric flux of `-1 xx 10^(3) Nm^(2) C^(-1)` to pass through a spherical Gaussian surface 10 cm radius centred on the charge.
If the radius of the Gaussian surface was doubled, how much flux would pass through the surface?

Explanation

There is no change in the electric flux, when the radius of Gaussian surface is doubled. It is because the charge enclosed by Gaussian surface remains same.
