Answer on Atomic and Nuclear Physics Question for dilshad shaikh
what are the similarities between nn and pp forces
The nuclear force between two nucleons is charge independent. By this we mean that the strong interaction between two protons or two neutrons or a neutron and a proton is the same. (Of course, there will be differing electromagnetic forces in these cases). Evidence for the charge independence of nuclear forces can be found in nucleon-nucleon scattering and in the binding energies of light mirror nuclei.
