Two nucleons are at a separation of one Fermi. Protons have a charge of\[+1.6\times {{10}^{-19}}C\]. The net nuclear force between them is \[{{F}_{1}}\], if both are neutrons, \[{{F}_{2}}\]if both are protons and \[{{F}_{3}}\] if one is proton and the other is neutron. Then:

A)  \[{{F}_{1}}={{F}_{2}}>{{F}_{3}}\]             

B)  \[{{F}_{1}}={{F}_{2}}={{F}_{3}}\]

C)  \[{{F}_{1}}<{{F}_{2}}<{{F}_{3}}\]             

D)  \[{{F}_{1}}>{{F}_{2}}>{{F}_{3}}\]
