The quantitative expression for the effect of these three variables on electric force
is known as
And it wasn't until 1785, and there were many that came before Coulomb, but in
1785 Coulomb formally published what is known as
Note that this satisfies Newton's third law because it implies that exactly the same
magnitude of force acts on q2 .
An equal and opposite force acts on the first charge, in accordance with Newton's
Electric Force of Two Charged Objects,
