Obtain a semiempirieal binding energy per nucleon formula. Using this as a guide, explain why the Coulomb force, which is only about  as strong as the internucleon attraction for two protons "in contact" (cf. Table 11.2), would eventually have to become a dominant factor in large nuclei. Assume that Z, N, and A increase in rough proportion to one another.
