Electrostatics
Electrostatics is the study of the forces between charged objects. The statics part of the name means the charges are not moving.
The examples collected here are the classic electrostatic configurations. Point charges, two examples of a line of charge, and a plane of charge. With just these simple geometries you will build up a good intuition about electric force.
