Coulomb's law is used to calculate the electrical attraction between 2 charged particles, what formula do I use to calculate an electrical attraction magnitude between 2 plates? Let's assume the first plate holds a charge of +3x10^-4 coulombs and the other one holds the same negative amount of charge (-3x10^-4), both plates area is 5 square centimetres and they are fully exposed and facing to each other. Also let me assume that the distance between them is 2 meters.
