When was the first force between electric charges measured quantitatively?
Quick Answer
Coulomb measured it in 1785.
The Full Story
Charles-Augustin de Coulomb quantified the force between electric charges in 1785. Using a torsion balance, he showed that electric force depends on the amount of charge and decreases with distance according to what became known as Coulomb's law. This was a foundational result in electrostatics and later influenced the development of electromagnetism. The unit of electric charge, the coulomb, is named after him.
