1. Consider the thin and uniformly charged rod has a linear charge density .. P b L (a) Find the electric potential at P. (b) From (a), find the electric field E 2. Using the Gauss's Law to prove the following (a) Any excess charge placed on a conductor on its surface (b) A closed, hollow conductor shields its interior from field due to the charges outside but does not shield its exterior from the fields due to charges placed inside it. (c) The electric field at the surface of a conductor is normal to the surface and o has a magnitude of EO 3. Consider the two long, cylindrical conductor, separated by a distance d form a capacitor, Cylinder 1 has charge density and radius aj and Cylinder 2 has charge density - and radius a2. Show that the capacitance per unit length is given approximately by - 1 C = ne, (w4" ) In where a is the geometric mean
