What is the strongest force?
What is the strongest force? force of gravity Can the strong force be repulsive? The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 10−15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm.
