4. Let cosider a solid nonconducting sphere with radis a. It has A gold layer (conducting) with negligible thickness covers the sphere. A ttal charge of -2Q is placed on this loyer. a) What is the eleitric field inside the sphere ? b) What is the electric field' outside the coated sphore? uniform +Q charge distribution in its volume. 4.
