(a) Using Gauss' law derive Coulomb's formula for the electric field due to an isolated point charge q . (b) A positive charge Q is uniformly distributed in a non-conducting sphere of radius R. Calculate the electric flux passing through the spherical surface of radius r concentric with the sphere for (i) r < R; (ii) r > R. |
