Solve the all given parts of following problem:
Problem: A very long, straight cylindrical conductor with radius R and length L carries a uniformly distributed net charge Q. This conductor is surrounded by a concentric cylindrical shell with inner radius 2R and outer radius 4R consisting of a linear dielectric material with dielectric constant k.
Part A: What are the bound surface charge densities at r = 2R and at r = 4R?
Part B: What is the bound volume charge density in the dielectric?
Part C: What is the potential difference between r = R and r = 5R?
I need help to find the bound surface charge densities.
