Problem: A long non-conducting cylinder has a charge density p = Alpha R, where Alpha = 6.53 C/m4 and r is in meters. Concentric around it is a hollow metallic cylindrical shell.
Part A: What is the surface charged density inside the hollow cylinder?
I need help to find the surface charged density inside the hollow cylinder.
