If a helium nucleus with a mass of 6.68 10-27 kg, a charge of +2e, and an initial velocity of 1.54 107 m/s is projected head-on toward a gold nucleus with a charge of +79e, how close will the helium atom 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.)
(a) How much does a 70.0 kg person weigh on the Earth? (b) How much would she weigh on the Moon (gmoon = 0.166g)? (c) How much would she weigh on a neutron star where gstar = 1.43×1011g?
