The dependence of nuclear force on distance between nucleons is not known precisely but approximate variation is shown graphically- From the above graph it can be concluded that-

[a] Nuclear force is repulsive for separation less than 0.5 fermi

[b] Nuclear force is attractive for separation less than 0.5 fermi

[c] Nuclear force is attractive for separation more than 0.5 fermi

[d] Nuclear force is negligible when the separation between nucleons is more than 10 fermi

A) a, c, d              

B) b, c, d

C) a                                 

D) b, c
