  • Physics XI | 1.4.4 Weak Nuclear Force

    1.4.4 Weak Nuclear Force The weak nuclear force appears only in certain nuclear processes such as the p-decay of a nucleus. In β-decay, the nucleus emits an electron and an uncharged particle called neutrino. The weak nuclear force is not as weak as the gravitational force, but much weaker than the strong nuclear and electromagnetic…

  • Physics XI | 1.4.3 Strong Nuclear Force

    1.4.3 Strong Nuclear Force The strong nuclear force binds protons and neutrons in a nucleus. It is evident that without some attractive force, a nucleus will be unstable due to the electric repulsion between its protons. This attractive force cannot be gravitational since force of gravity is negligible compared to the electric force. A new…
