alleryWhy must the nuclear binding force be much stronger than the Coulomb force?
AIt must beat neutrino attraction
BIt must beat proton repulsion
CIt must beat neutron repulsion
DIt must beat electron attraction
Answer & Solution
Correct answer: B. It must beat proton repulsion
1. Protons inside a nucleus all carry positive charge.
2. They repel each other electrically at very short range.
3. The nuclear binding force has to dominate over the Coulomb repulsive force between protons.
4. That happens only because the nuclear force is much stronger.
