..27 Figure 23-37 is a sec- tion of a conducting rod of ra- dius R = 1.30 mm and length L - 11.00 m inside a thin- walled coaxial conducting cy- lindrical shell of radius R = RI 10.0R, and the (same) length L. The net charge on the rod is Q1 = +3.40 X 10-12 C; that on the shell is @2 - -2.00Q1. What are the (a) magnitude E and (b) direction (radially in- Fig. 23-37 Problem 27. ward or outward) of the elec- tric field at radial distance r = 2.00R2? What are (c) E and (d) the direction at r - 5.00R ? What is the charge on the (e) interior and (f) exterior surface of the shell? SSM WWW S
