• Gravity and the electromagnetic force act on small objects while the nuclear forces act on large objects.
Gravity and the electromagnetic force act on large objects while the nuclear forces act on small objects.

Answer 1

Gravity and the electromagnetic force have infinite ranges while the nuclear forces have very small ranges.

Reason: Gravity and electromagnetism are mediated by (effectively) massless carriers (gravitons/photons) so their influence extends indefinitely; the nuclear forces are short-range (residual strong force from massive pion exchange and weak force from massive W/Z bosons, plus confinement of the strong interaction), so they act only over subatomic distances.
