BRAINCAKEStrong Nuclear Force
We can estimate the size of the strong nuclear force by working out the force of repulsion of the protons in the nucleus using Coulombs Law. Given that the diameter of a nucleus has been measured from electron diffraction experiments, it follows that nucleons are evenly spaced at about 1fm apart and the strong nuclear force acts only between adjacent nucleons.
