Fusion is not easy to achieve since the protons' like charges causes a huge electric-force repulsion between them when they are at the small distances (on the order of 1 fm = 10-15 7) required to form a nucleus. ▼ Part A To see why fusion only occurs at very high temperatures (like at the center of stars), consider this basic problem: Two protons are initially at rest and very far apart from each. With what minimum speed must one of the protons be launched in order for it to overcome the electric repulsion and to end up within 1.9 fm of the other? (For simplicity, assume the other proton is being held in place.)
