Vedclass · Answer

(A) The binding energy $(BE)$ is the energy equivalent to the mass defect $(\Delta m)$,which is the difference between the total mass of the constituent nucleons and the actual mass of the nucleus.The mass defect is given by $\Delta m = [ZM_p + (A-Z)M_n] - M(A, Z)$.According to Einstein's mass-energy equivalence principle,$BE = \Delta m 	imes c^2$.Substituting the expression for $\Delta m$,we get $BE = [ZM_p + (A-Z)M_n - M(A, Z)] 	imes c^2$.Dividing by $c^2$,we have $BE/c^2 = ZM_p + (A-Z)M_n - M(A, Z)$.Rearranging the terms to solve for $M(A, Z)$,we get $M(A, Z) = ZM_p + (A-Z)M_n - BE/c^2$.Thus,the correct relation is $M(A, Z) = ZM_p + (A-Z)M_n - BE/c^2$.

If $M(A, Z)$,$M_p$,and $M_n$ represent the masses of the nucleus ${}_{Z}^{A}X$,proton,and neutron in $u$ units respectively $(1u = 931.5 \, MeV/c^2)$,and $BE$ represents the binding energy in $MeV$,then which of the following relations is correct?

Let ${m_p}$ be the mass of a proton,${m_n}$ the mass of a neutron,${M_1}$ the mass of a $_{10}^{20}Ne$ nucleus,and ${M_2}$ the mass of a $_{20}^{40}Ca$ nucleus. Then:

Nucleus $A$ having $Z=17$ and an equal number of protons and neutrons has $1.2 \, MeV$ binding energy per nucleon. Another nucleus $B$ of $Z=12$ has a total of $26$ nucleons and $1.8 \, MeV$ binding energy per nucleon. The difference in binding energy of $B$ and $A$ will be $........... \, MeV$.
