Is it possible to caculate the electric potential energy and the gravitational potential energy between two nucleon of deuterium (1 proton, 1 neutron), if we know the binding energy of deuterium is 2.23 (MeV), and the distance between them is 1 (fm)?
Please help me! I'm really confused about this exercise :(
Thanks in advance

The gravitational energy is -Gmm'/r.
There is no electric PE, but there is magnetic energy between the two magnetic moments.
These energies are negligible compared to the 2,23 whic is due to the nuclear force.
