Coulomb force
Coulomb force
Force between two electric charges. The magnitude of the force F is proportional to the product of the two charges, q and q, divided by the square of the distance r between them, or F = kqq/r2, where k is a constant that depends on the measurement system being used. The Coulomb force can be one of repulsion, such as the force between two objects having like charges, or it can be attractive, such as the force between two objects having opposite charges.
