Coulomb's law states that the force between particles depends on their charge. But protons and electrons have equal but opposite charges. Shouldn't the formula simply have constants with the only changes required being the signs?

Yes. The charges are additive.A follow on question... if you have 2 protons, then it's quite trivial to calculate. What if I have 2 clumps of protons. Are the charges simply additive?
