Solve the all parts of given question:
Question: A long non-conducting cylinder has a charge density p = Alpha R, where Alpha = 6.53 C/m^4 and r is in meters. Concentric around it is a hollow metallic cylindrical shell. Assume the length L is very long compared to the diameter of the shell, and neglect edge effects. The Coulomb constant is 8.8542 × 1012 C2/N/m2.
Part A: What is the surface charge density inside the hollow cylinder?
Part B: What is the direction of the electric field at 15.4 cm from the central axis?
I need help to find the surface charge density inside the hollow cylinder.
