Compute all parts of given question:
Question: An infinitely long straight wire is uniformly charged with a positive linear charge density +lambda. It is surrounded by an insulating hollow cylinder of inner radius R and outer radius 2R. The hollow cylinder has a uniform charge density rho.
Part A: Determine the value of rho if the electric field vanishes at every point outside the cylinder?
Part B: Determine the electric field in the region 0?
Part C: Determine the electric field in the region R?
