In a Rutherford scattering experiment, an α-particle (charge = +2.00e) heads directly toward a gold nucleus (charge = +79.0e). The α-particle had a kinetic energy of 7.95 MeV when very far (r → ∞) from the nucleus. Assuming the gold nucleus to be fixed in space, determine the distance of closest approach. (Hint: Use conservation of energy with PE=keq1q2/r).
