A charge of uniform linear density 2.20 nC/m is distributedalong a long, thin, nonconducting rod. The rod is coaxial with along conducting cylindrical shell (inner radius = 4.00 cm, outerradius = 9.00 cm). The net charge on the shell is zero. (a) What isthe magnitude of the electric field at distance r = 13.0 cm fromthe axis of the shell? What is the surface charge density on the(b) inner and (c) outer surface of the shell?
