हिन्दीA nucleus with mass number \( 240 \) breaks into two fragments each of mass number \( 120 \), the binding energy per nucleon of fragmented nuclei is \( 7.6\text{ MeV} \) while that of fragments is \( 8.5\text{ MeV} \). The total gain in the Binding Energy in the process is:
Correct answer · Option 3
216 MeV
Explanation
Total Binding Energy initially = \( 240 \times 7.6\text{ MeV} \). Total Binding Energy finally = \( 2 \times 120 \times 8.5\text{ MeV} = 240 \times 8.5\text{ MeV} \). Gain = \( 240 \times (8.5 - 7.6) = 240 \times 0.9 = 216\text{ MeV} \).
