Problem: In 1911, Ernest Rutherford discovered the nucleus of the atom by observing the scattering of helium nuclei from gold nuclei. If a helium nucleus with a mass of 6.68 x 10-27 kg, a charge of +2e, and an initial velocity of 1.26 x 107 m/s is projected head-on toward a gold nucleus with a charge of +79e,
Part A: How close will the helium atom come to the gold nucleus before it stops and turns around?
I need help to solve the above question and assume the gold nucleus is held in place by other gold atoms and does not move.
