in nucleus we have protons and neutrons . neutrons have no charge but protons have so they should repel each other ,but they don't why??

From our current knowledge of the physical world, particles can intereact with each others thanks to 4 differents "interaction forces":
Gravity, that attracts particles on their energy content;Electromagnetism, that attracts or repels particles based on their electric charge;Strong nuclear force, that attracts particles based on their strong nuclear charges, a.k.a. "color charges";Weak nuclear force, that makes neutrons unstable so they transform into protons (ok, at this level of discussion, this one seems like a weird "force", but that is all you need to know!)So YES, protons do repel each others in the nucleus due to the positive electric charges they posses, BUT, they also are massive particles and they possess color charges. And the same holds for neutrons: massive and color charge.

why neutron are converted in protons ? why not electrons ? if they were converted into electrons then nucleus would me more stable
