Semi-empirical mass formula — UPSC Physics Optional IFoS 2022 Paper II

Write the semi-empirical mass formula. Establish the relation A \approx 2Z, where A is mass number and Z is atomic number of the light nuclei, using this semi-empirical mass formula. [Given : good fitting coefficients for Coulomb energy (a_c) = 0\cdot 71\text{ MeV}, for asymmetry energy (a_n) = 22\cdot 7\text{ MeV}]
