Which is not true of the weak nuclear force? a) it is a repellent force. b) it acts over a shorter range than the strong nuclear force. c) it is an attractive force. d) it is weaker than the strong nuclear force.

The weak nuclear force is one of the fundamental forces:

Is a force that is responsible of some radiative phenomenoms, like the beta decay.

The intensity is way smaller than the one of the strong interaction, but this is because it acts in a way smaller range. And this can produce atractive and repulsive interactions.

So options D and B can be discarded.

And this force can be repulsive or attractive depending on the phenomena, so the options that are wrong are A and B, because the interaction is both things, not only one.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
