SOLUTION: (C) Dimensional analysis works fine here. However, you can also derive needed expression using Newton’s second law and Bohr’s quantization rule. Indeed, the former gives , while the later . From these two equations (excluding ): . Potential energy: . The total energy: . Substituting into the expression for the total energy yields . To account for the motion of the nuclei we can treat in the last equation as the reduced mass. Thus, choice (C).
