Answer:
B) neutron keep protons apart so they don’t repel each other
Explanation:
Neutrons are of almost same mass as that of protons mass or we can say it is slightly greater than the mass of proton
There is no charge on the neutrons as they are neutral and they resides inside the nucleus.
since nucleus is a small region where large number of protons and neutrons exists so in this small region protons must have large repulsion force between them but since this repulsion force is counterbalanced by the strong nuclear force between the neutrons and protons so here role of neutrons is to provide sufficient strong force to bound the nucleons together
so here correct answer will be
B) neutron keep protons apart so they don’t repel each other
