Question

Which property distinguishes nuclear force from gravitational and electromagnetic forces?

Options

• It acts between all particles

• It is inversely proportional to the square of distance

• It is a saturated, short-range force

• It depends on the charge of the particle

Answer 1

It is a saturated, short-range force

Explanation:

Nuclear force acts only within ~1–2 fm and each nucleon interacts only with its nearest neighbours (saturation). Gravitational and electromagnetic forces are long-range and follow inverse square law.
