46. If M(A ; Z), M_p and M_n denote the masses of the nucleus _Z^A X , proton and neutron respectively in units of u (1 u =931.5 MeV / C ^2 ) and BE represents its bonding energy in MeV , then
Options
- AM(A, Z)=Z M_p+(A-Z) M_n+ BE / C^2
- BM(A, Z)=Z M_p+(A-Z) M_n- BE / C ^2
- Caligned & M(A, Z)=Z M_p+(A-Z) M_n+B E aligned
- Daligned & M(A, Z)=Z M_p+(A-Z) M_n-B E aligned
Correct answer
B. M(A, Z)=Z M_p+(A-Z) M_n- BE / C ^2
Step-by-step solution
BE = [ ZM _ p +( A - Z ) M _ n - M ( A , Z ) ] C ^2
