1. The problem statement, all variables and given/known data Sketch the equipotential surfaces which result from the following charge configurations: (a) a point charge (b) a spherically symmetric charge distribution (c) a very large, plane, uniformly-charged sheet (d) a long, uniformly-charged cylinder (e) an electric dipole. 2. Relevant equations 3. The attempt at a solution a) and e) I have but the rest I cant find... Can someone show me a good website or something, I need these for an assignment.
