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 = +3.60 10-12C that on the shell is Q2 = ?3.00Q1.

The figure below is a section of a conducting rod

(a) What is the magnitude E of the electric field at a radial distance of r = 2.50R2?

I got an answer of 0.181 N/C but that is wrong.. Please help!!

Answer #1

Using gauss law. ere Area A = 2TrL r = 2.50R -2.50 (10R) 250 10(1.30x10* m) 32.5x103 m 23.60x10-2 c =-7.2×10-12 C Hence -7.2x
