Equipotential Surfaces for Different Charge Configurations: Where to Find Them?

[pat666]

Homework Statement

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.

Homework Equations

The Attempt at a Solution

a) and e) I have but the rest I can't find...
Can someone show me a good website or something, I need these for an assignment.
