Question

How can you prove that size of nucleus is very small from Rutherford scattering model?​

Answer 1

Answer:

$By shooting alpha particles of kinetic energy 5.5 MeV, the point of closest approach was estimated to be about 4×10-14m. Since the repulsive force acting here is Coulomb repulsion, there is no contact. This means that the size of the nucleus is smaller than 4×10-14m.$
