Cheng, P. 317 . In class, we found the electric eld around an innitely long uniform line of charge by applying Gausss Law. This was possible because the eld in that case is a function of radial distance r only and any coaxial cylindrical surface around an innite line of uniform charge is an equipotential surface. In practice, of course, all charge sources must be of nite length and, as a result, the equipotential surfaces are not coaxial cylinders. Given a nite line of charge with uniform linear charge density and length L , nd the potential (with reference potential of zero at innity) on a coaxial cylindrical surface of radius R as a function of x and plot it....
