A nucleus with mass number $240$ breaks into two fragments each of mass number $120$, the binding energy per nucleon of unfragmented nuclei is $7.6$ MeV while that of fragments is $8.5$ MeV. The total gain in the Binding Energy in the process is :
Answer: (A) $216$ MeV
Initial binding energy: $240 \times 7.6 = 1824$ MeV.
Final binding energy: $2 \times 120 \times 8.5 = 2040$ MeV.
Gain: $2040 - 1824 = 216$ MeV.
