The figure is a section of a conducting rod of radius RI = 1.60 mm and length L = 13.00 m inside a thin-walled coaxial conducting cylindrical shell of radius R2 = 12.8R1 and the (same) length L. The net charge on the rod is QI = +3.73 x 10-12 C; that on the shell is QI = -2.18Q1. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.34R2? What are (c) E and (d) the direction at r = S.09R1? What is the charge on the (e) interior and (f) exterior surface of the shell? (a) (c) (e) (f) Number inward Number Units N/corv,'m 063 outward v Number Number -3.73+12 -4.4+12 Units Units Units
