NEET2021Physics-Nuclear Binding Energy
NEET 2021 Physics Energy Gain in Fission MCQ Question
Type: MCQ-numerical-Medium-Class 12
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 :
A
0.9 MeV
B
9.4 MeV
C
804 MeV
D
216 MeV
Correct Answer
Option D
Detailed Explanation
The gain in binding energy is the difference in total binding energy before and after the reaction. The gain is (8.5 - 7.6) × 240 = 804 MeV.
