A system of consists of two infinitly long concentric copper pipes. The radius of the inner pipe is 1.00m and it has a charge per unit length lamba=2.00 microC/m. The outer pipe has a radius of 2.00m and a charge per unit length of lamba=-1microC/m. The thickness of the two pipes is negligible.
a) Use Gauss' law to find the electric field as a funciton of r inside the smaller pipe.
b) Use Gauss' law to find the electric field as a function of r between the pipes.
c) Use Gauss' law to find the electric field as a fuction of r outside of the larger pipe.
