Two nucleons are at a separation of \[1\times {{10}^{-15}}m\]. The net force between them is \[{{F}_{1}}\], if both are neutrons, \[{{F}_{2}}\] if both are protons and \[{{F}_{3}}\] if one is a proton and other is a neutron. In such a case           [KCET (Med.) 2000, 05; UPSEAT 2005]

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

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

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

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