This is from Advanced Physics by Adams and Allday. Spread 8.26, Q 2.
a) The strong nuclear force cannot fall off as an inverse-square law. Why not?
b) Give a reason for thinking that the strong nuclear force must become a repulsion at very short range.
The Attempt at a Solution
I have searched the Internet for phrases in the questions and found nothing satisfactory. The text book mentions quarks but nothing of colour, up/down, or mesons so I'm guessing the answers don't require that level of theory.
For a) the expression "fall off" must mean reducing from a maximum ...
For b) it seems simplistic to say the nucleons can't touch.
