Question

2. This problem will help you better understand the energy landscape model used in the lecture notes. You are asked to answer the following two questions: (a) Calculate the electrostatic energy of a charge $Q$ distributed uniformly throughout a sphere of radius $R$. (b) Given that $^{27}_{14}Si$ and $^{27}_{13}Al$ are \"mirror nuclei\" with identical ground states except for charge, estimate the radius $R$, if the mass difference between these two mirror nuclei is 6.0 MeV. Assume that this mass difference arises solely due to the difference in the electrostatic energy of these two nuclei. (Do not use the $R = R_0A^{1/3}$ relation for this estimation.)
