In 1910 Rutherford performed a classic experiment in which he Grected a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of the particles scattered almest. directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to propote the existence of a very dense concentration of positve cha at the center of an atom-the atomic nucleus. The alpha particle has a charge of +2e and the gold nueleus a charge of +79e. 50ppose that an alpha particle is initially a great distance from the cols, has a kinetc energy of 6.22MeV(6.22106 eV), and is headed directly at a gold nucieus. How close will the partide come to the center of the nucleus? Treat thie nucien and the aloha partide as point charens
