Protons are positively, electrons are negatively charged but protons in an atom does not repeal?why?

Of course protons repel each other with a electrostatic force that is equal to the electrostatic force of repulsion between two electrons. However, since the protons are inside the nucleus, unlike electrons, they are affected by nuclear forces too. Nuclear forces are more dominant than the electrostatic forces, and they are always attractive, and thereby the electrostatic force of repulsion isn't observed. The gravitational force of attraction for protons is also greater than that for electrons due to their greater weight. However, nuclear force is the dominant force.
