Question

Quizplus · Accepted Answer

The electromagnetic and gravitational forces have an infinite range because they are mediated by massless particles (photons for electromagnetic and gravitons for gravity, theoretically). The strong and weak nuclear forces have finite ranges due to the massive particles (gluons and W/Z bosons) that mediate them.
