The nuclear force is short-range: beyond a distance of a few times the typical nuclear dimension the force falls off to zero. In contrast, the electric force decreases as two charged particles (protons) become farther apart, but it falls off inversely as the square of the distance, as gravity does.

What are short range forces with examples?

Short range forces happen when the centers of the molecules are separated by three angstroms (10^-8 cm) or less. Short range forces tend to be repulsive, where the long range forces that act outside the three angstroms range are attractive. Long range forces are also known as Van der Waals forces.

What is short range force in physics?

[′shȯrt ¦rānj ′fȯrs] (physics) A force between two particles which is negligible when the distance between the particles is greater than a certain amount; in particular, nuclear forces whose range is several times 10^-15 meter.
