Here is a question I did not know how to answer. What is the directionality
of the so-called "weak" force, is it attractive, repulsive or both? I do
know gravitational and "strong" forces are always attractive and that the
electromagnetic forces can be either attractive and repulsive.

P.S.
By "strong" I mean forces between nucleons (ignoring their inner structure).
