Due to the presence of a charge at the centre of a sphere of radius 10 cm, the electric flux passing through the surface of the sphere is `-6xx10^(3)N.m^(2).C^(-1)`.
(i) What is the magnitude of charge inside the sphere?
(ii) If a concentric spherical Gaussian surface with a radius double that of that of the sphere is taken, what will be the amount of electric flux now passing through this surface?

Answer

(i) `-5.31xx10^(-8)C`, (ii) remains the same as before
