6. At a radius of less then 0.5 Fm, the SNF is repulsive. Answers for you to check your
APPLICATION




This is to prevent the atom from collapsing. From responses.
between 0.5-3 or 4 Fm, the SNF is attractive to
overcome the electrostatic forces of repulsion
between protons. Beyond 3/4 Fm the effect of
the SNF is negligible.
