Figure 23 38 Is A Section Of A Conducting Rod Of Radius R1 1 47 Mm And Length L

Figure 23-38 is a section of a conducting rod of radius R1 = 1.47 mm and length L = 12.10 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 = +3.73 × 10-12 C; that on the shell is Q2 = -2.20Q1. What are the (a) magnitude E and (b) direction (radially inward (type 1) or outward (type 0)) of the electric field at radial distance r = 2.32R2? What are (c)E and (d) the direction (1 for inward, 0 for outward) at r = 5.15R1? What is the charge on the (e) interior and (f) exterior surface of the shell? Give electric fields in N/C and charges in Coulombs.
