Note: Your answer is assumed to be reduced to the highest power possible.
In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of
the particles scattered almost directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to
propose the existence of a very dense concentration of positive charge at the center of an atom-the atomic nucleus. The alpha particle has a charge of
+2e and the gold nucleus a charge of +79e. Suppose that an alpha particle is initially a great distance from the gold, has a kinetic energy of 5.44 MeV
(5.44 x 106 eV), and is headed directly at a gold nucleus. How close will the particle come to the center of the nucleus? Treat the nucleus and the alpha
particle as point charges.
