Question

For a nucleus AAX having mass number A and atomic number Z
A. The surface energy per nucleon $(b_s)=−a_1A^{\frac{2}{3}}$
B. The Coulomb contribution to the binding energy $b_c=−a_2\frac{Z(Z−1)}{A^{\frac{4}{3}}}$
C. The volume energy bv=a3A
D. Decrease in the binding energy is proportional to surface area.
E. While estimating the surface energy, it is assumed that each nucleon interacts with 12 nucleons. ( a1,a2 and a3 are constants)
