A gold nucleus is located at the origin of coordinates, and a helium nucleus initally at the coordinates (0, 2 A) moves to the position (0, 1 A).
A: Calculate the magnitude of the force on the electron at each separation.
B: Calculate the change in the potential energy of the two nuclei.
C: Calculate the change in the kinetic energy of the helium nucleus assuming its value at 2 A is 2.0 MeV if you assume the gold nucleus is so massive that it stays at the origin.
