Nuclei

Question:

When we draw the variation of the potential energy of a pair of nucleons with their separations, then

Options:

the force is attractive when separation between them is greater than 0.8 fm

the force is repulsive when separation between them is greater than 0.8 fm

the force is attractive when separation between them is less than 0.8 fm

the force is independent of their seperation

Correct Answer:

the force is attractive when separation between them is greater than 0.8 fm

Explanation:

The nuclear force is repulsive when the separation is less 0.8 fm

It is attractive when the separation is greater than 0.8 fm
