Let `F_pp, F_pn and F_nn` denote the magnitudes of the nuclear force by a proton on a proton, by a proton on a neutron and by a neutron on a neutron respectively. When the separation is `1 fm`,

Let F_pp, F_pn and F_nn denote the magnitudes of the net force by a proton on a proton, by a proton on a neutron and by a neutron on a neutron respectively. Neglect gravitational force. When the separation is 1 fm ,

The quark content of proton and neutron are respectively

The quark content of proton and neutron are respectively
