Yes that's true when it comes to interactions between neutron to proton, proton to proton, etc, but the strong forces in the proton itself, between the uud quarks, is controlled by gluons.
I've been trying to find a source for this somewhere, but I always end up with different sources explaining what holds protons and neutrons together in the nucleus of an atom. I know that the gluons hold them together, but I'm not sure exactly how they do this, and what type of transfers occur...
After calculating the force upon an electron and a force upon a proton in the atom of hydrogen, my result was a force of ≈8.2x10-8 Newtons acting upon the electron and proton each.
If found this by using the formula Fe = (ke q1q2)/r2
Taking this number, I then applied it in the formula F = ma...
