In Rutherford’s original experiment, alpha particles (α) were shot toward a gold foil. Gold has an atomic number of 79. An α had initial kinetic energy of about 6 MeV. When an α was closest to a gold nucleus, it stopped completely by the electric repulsive force between the two nuclei. Assume all the α kinetic energy was converted to electric potential energy. The closest distance (center to center) between the two nuclei is _____ x 10-15 meter.

Compute Na (10⁰) Na (20°). p2 Rutherford's scattering model assumes that the alpha particles experience a Coulomb repulsion, F = KqZe from the nucleus of the foil's atom. If, in a head-on collision the alpha particle has enough energy to get inside a uniformly charged Kqa Zer nucleus of radius R, the force law would change to F = R³ " point-nucleus…
