Consider a solid cylinder of length 1 and radius a. assume the length 1 to be very large, such that all edge effects of the cylinder can be ignored. the cylinder has surface charge density o and volume charge density p(r) given by: 1 kr2 for r a. i) determine the electric field e(r) and potential v(r) for r a. ii) a second hollow cylinder of equal length 1, radius b such that b> a and surface charge density o is placed around the first cylinder. determine the effect on the electric fields in the regions: p
