Two protons in an atomic nucleus repel each other, but they are also attracted to each other. Explain.?

Answer 1

They repel each other from having a similar positive charge (like charges repel). They are bound together in the nucleus by the strong nuclear force. It is when that bond is broken in the nucleus containing protons and neutrons that a very large amount of energy is released. In simple terms, I like to think of it as trying to superglue magnets together with their repulsive sides together. They try to push apart, but once they are in contact, the superglue binds them. This is simplified, but makes a reasonable picture in my head.

Answer 2

There are two forces at work. One is electromagnetism, in which objects of the same charge repel. In a nucleus, protons, which are positively charged, repel each other, but the repulsion is overpowered by the residual strong force in the form of exchange of mesons. At the short distances that this force interacts, it is about 20x stronger than electromagnetism.

Answer 3

The repulsion between protons is due to the Coulomb force. The attraction between nucleons ( protons and neutrons ) is due to the strong nuclear force. Neutrons provide additional strong force without any corresponding repulsive Coulomb force, which is why heavy nuclei have more neutrons than protons.

Answer 4

They repel one yet another from having an identical beneficial fee (like costs repel). they're sure mutually interior the nucleus via the reliable nuclear tension. that's while that bond is broken interior the nucleus containing protons and neutrons that a very great volume of capability is released. in basic terms, i like to think of of it as attempting to superglue magnets mutually with their repulsive aspects mutually. they attempt to push aside, yet while they're in touch, the superglue binds them. this is simplified, yet makes a actual looking photograph in my head.
