Whose ideas did Charles Coulomb compare electric forces to?

A) Albert Einstein

B) Isaac Newton

C) Georg Ohm

D) James Watts

E) Allesandro Volta

I chose B) Isaac Newton ... is that correct?

He compared is to B) Isaac Newton

Isaac Newton has earlier on came up with his formula on gravitation as;

F = GMm/r²

Later on Charles Coulomb came up with his formula on electrostatic force as:

F = kQq/r²

You can see his formula is similar to that earlier formulated by Isaac Newton on gravitation.
