The figure below is a section of a conducting rod of radius R1 = 1.30 mm and length L = 11.00 m inside a thick-walled coaxial conducting cylindrical shell of radius R2 = 10.0R1 and the (same) length L. The net charge on the rod is Q1 = +1.50 10-12C that on the shell is Q2 = −2.00Q1. (a) What is the magnitude E of the electric field at a radial distance of r = 3.00R2? -0.629 Incorrect: Your answer is incorrect. N/C (b) What is the direction of the electric field at that radial distance? inward Correct: Your answer is correct. (c) What is the magnitude E of the electric field at a radial distance of r = 5.00R1? (No Response) N/C (d) What is the direction of the electric field at that radial distance? outward Correct: Your answer is correct. (e) What is the charge on the interior surface of the shell? -1.5e-12 Correct: Your answer is correct. C (f) What is the charge on the exterior surface of the shell?
