SUMMARY
The formula for calculating electrical potential is given by V = Ke x q/r, where Ke is Coulomb's constant, q is the charge, and r is the distance from the charge. In the context of 4.00 MeV alpha particles scattering off gold nuclei, the attempt to solve for the distance of closest approach (r) was incorrect due to a misunderstanding of energy conservation principles. The kinetic energy of the alpha particle must be considered, as it is 4.00 MeV when far from the nucleus, and this energy transforms as the particle approaches the nucleus. The correct approach involves applying mechanical energy conservation rather than equating electrical forces directly.
