in a nucleus there was lot of protons which carries positive charge and as we know that positive charges repel each other so is protons also repel each other if yes why?if no why?

Expert Answer:

These forces exist due to the fact that in the nucleus there are also neutrons which buffer the repulsive forces between the protons, therefore stabilizing them. Sometimes if the proton to neutron ratio is too high (too many protons versus neutrons) the nucleus will undergo positron emission or electron capture and emit radiation in the forms of gamma rays.
