If the electromagnetic force was the only force in play if the coulomb force was the only thing happening, these guys would just run away form each other they would repel each other and so, the only reason that they're able to stick to each other is that there's even stronger force than the electromagnetic force operating at these very, very small distances so if you get two of these protons close enough together, and the strong force applies only over very, very small distances subatomic, or I should even say sub-nucleic distances then the strong interaction comes into play so then you have the strong interaction actually keeping these charges together
