The range $R$ of a force field is inversely related to the mass $M$ of the mediating particle according to the formula derived from quantum field theory, which is $R \proportional \frac{1}{M}$. This relationship is a consequence of the uncertainty principle, indicating that heavier mediating particles result in shorter-range forces.
