In 1911, Ernest Rutherford discovered the nucleus of the atom by observing thescattering of helium nuclei from gold nuclei. If a helium nucleus with a mass of 6.68 10-27 kg, a chargeof +2e, and an initial velocity of 1.50 107 m/s is projected head-on toward a gold nucleus with a chargeof +79e, how close will the helium nucleus come to the gold nucleus before it stops and turns around?(Assume the gold nucleus is held in place by other gold atoms and does not move. Also assume that theinitial distance of the helium nucleus from the gold nucleus is very large.)
