3. (20 pts) The figure below is a section of a conducting rod of radius R1=1.0 mm and length L=10.00 m inside a thin-walled coaxial conducting cylindrical shell of radius R2=10.0R1 and the (same) length L. The net charge on the rod is Q1=+3.50*10-12 C; that on the shell is Q2=-2.00Q1. What are the magnitude E and direction (radially inward or outward) of the electric field (a) at r=2.00R1? (b) at radial distance r=2.00R2? RI Q2
