Two nucleons are at a separation of 1 fm. The net force between them is F1, if both neutrons, F2 if both are protons and F3 if one is a proton and the other is a neutron.

Question

Two nucleons are at a separation of 1 fm. The net force between them is F1, if both neutrons, F2 if both are protons and F3 if one is a proton and the other is a neutron. (A) F1 > F2 > F3 (B) F2 > F1 > F3 (C) F1=F3 > F2 (D) F1=F2 > F3

Nuclear force of attraction between any two nucleons

(n - n

,

p - n, p - n)

is same. The difference comes up only due to electrostatic force of repulsion between two protons.

∴ F_{1} = F_{3} \neq = F_{2}

As

F_{2} < F_{3} > F_{1}

∴ F_{1} = F_{3} > F_{2}

Q. Two nucleons are at a separation of $1 f m$ . The net force between them is $F_{1}$ , if both neutrons, $F_{2}$ if both are protons and $F_{3}$ if one is a proton and the other is a neutron.

$F_{1} > F_{2} > F_{3}$

$F_{2} > F_{1} > F_{3}$

$F_{1} = F_{3} > F_{2}$

$F_{1} = F_{2} > F_{3}$

Nuclear force of attraction between any two nucleons $(n - n$ , $p - n, p - n)$ is same. The difference comes up only due to electrostatic force of repulsion between two protons.
$∴ F_{1} = F_{3} \neq = F_{2}$
As $F_{2} < F_{3} > F_{1}$
$∴ F_{1} = F_{3} > F_{2}$

Q. Two nucleons are at a separation of 1fm. The net force between them is F1​, if both neutrons, F2​ if both are protons and F3​ if one is a proton and the other is a neutron.

F1​>F2​>F3​

F2​>F1​>F3​

F1​=F3​>F2​

F1​=F2​>F3​
