What does Coulomb's Law describe?

• The relationship between electric current and magnetic fields

• The force between two charges being directly proportional to the product of their charges and inversely proportional to the square of the distance between them

• The rate of flow of electric charge

• The resistance offered by a material to the flow of electric current
