If in a nuclear fusion process the masses of the fusing nuclei be m_(1) and m_(2) and the mass of the resuktant nucleus be m_(3) , then

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. The correct statements about nuclear force is/are
