AIPMT MAINS 2010 Physics Nuclear Fusion MCQ Question
Type: MCQ-numerical-Medium-Class 12
The binding energy per nucleon in deuterium and helium nuclei are 1.1 MeV and 7.0 MeV, respectively. When two deuterium nuclei fuse to form a helium nucleus the energy released in the fusion is
A
23.6 MeV
B
2.2 MeV
C
28.0 MeV
D
30.2 MeV
Correct Answer
Option A
Detailed Explanation
The energy released ΔE = (28 − 4.4) MeV = 23.6 MeV. This is calculated by considering the difference in binding energy per nucleon before and after the fusion.
