The figure is a section of a conducting rod of radius R1 = 1.20 mm and length L = 13.80 m inside a thin-walled coaxial conducting cylindrical shell of radius R2 = 10.1R1 and the (same) length L. The net charge on the rod is Q1 = +3.41 × 10-12 C; that on the shell is Q2 = -2.33Q1. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.10R2? What are (c) E and (d) the direction at r = 5.31R1? What is the charge on the (e) interior and (f) exterior surface of the shell?
