Repeal Problem, but now let the outer shell have charge ?4?q?. As in Problem, the inner shell has charge +2?q?. Problem: Concentric Spherical Shells. A small conducting spherical shell with inner radius a and outer radius ?b is concentric with a larger conducting spherical shell with inner radius ?c and outer radius ?d (Fig.) The inner shell has total charge +2?q?, and the outer shell has charge +4?q?. (a) Calculate the electric field (magnitude and direction) in terms of ?q and the distance ?r from the common center of the two shells for (i) ?r < ?a; (ii) ?a < ?r < ?b?; (iii) ?b < ?r < ?c?; (iv) ?c < ?r < ?d?; (v) ?r > ?d. Show your results in a graph of the radial component of as a function of ?r?. (b) What is the total charge on the (i) inner surface of the small shell; (ii) outer surface of the small shell; (iii) inner surface of the large shell; (iv) outer surface of the large shell? Figure:
