Definition
1.Unlike charges attract;Like charges repel
2.Coulombs law:electrostatic force directly proportional to charges;Inverse proportion to square of distance btw.
3.Charge is evenly distributed throughout or on a surface of a conductor.
4.Charge is concentrated on sharpest curve of conductor. |
