A point charge causes an electric flux of $−1.0 \times 10^3 Nm^2/C$ to pass through a spherical Gaussian surface of $10.0\; cm$ radius centered on the charge. If the radius of the Gaussian surface were doubled, how much flux would pass through the surface?

1 Answer

$–10^3 N m^2/C;$ because the charge enclosed is the same in the two cases.
Hence A is the correct answer.
