(c16p19) In Rutherford's famous scattering experiments (which led to the planetary model of the atom), alpha particles (having charges of +2e and masses of 6.64×10-27 kg) were fired toward a gold nucleus
with charge +79e. An alpha particle, initially very far from the gold nucleus, is fired at 4.60×107 m/s directly toward the gold nucleus as in Figure P16.19. How close does the alpha particle get to the gold
nucleus before turning around? Assume the gold nucleus remains stationary.
