(ii) A charge of -338e is uniformly distributed over one face of the circular disk of radius 3.80 cm. Determine the surface charge density over that face?
(iii) A charge of -338e is uniformly distributed over the surface of the sphere of radius 2.20 cm. Determine the surface charge density over that surface?
(iv) A charge of -338e is uniformly spread via the volume of a sphere of radius 3.30 cm. Determine the volume charge density in that sphere?
