Two nucleons are at a separation of `1 xx 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.

Options

A. `F_(2)gtF_(1)gtF_(3)`
B. `F_(1)=F_(2)=F_(3)`
C. `F_(1)=F_(2)gtF_(3)`
D. `F_(1)=F_(3)gtF_(2)`

Answer

D

Explanation

`Fe larr underset("proton")overset(F=2F_(n)-Fe)(o)rarrF_(n)`
`F_(2)lt F_(n), F_(1) = F_(3) = F_(n)`
`F_(1) = F_(3) gt F_(2)`
