A charge of uniform linear density 2.20 nano Coulombs per meter is distributed along a long, thin, nonconducting rod. The rod is coaxial with a long conducting cylindrical shell (inner radius = .0600 m, outer radius = .104 m). The net charge on the shell is zero. a) What is the magnitude (in N/C) of the electric field at distance r = 16.4 cm from the axis of the shell. b) What is the charge density on the inner surface of the shell? c) What is the charge density on the outer surface of the shell? So that is the full question. I just need help with part C. I figured out the answer to part a and b. Any insight on part C. I'm thinking it might be 0, but I'm not sure. Any help would be appreciated.
