AIPMT PRELIMS 2006 Physics Nuclear Binding Energy MCQ Question
Type: MCQ-numerical-Medium-Class 12
The binding energy of deuteron is 2.2 MeV and that of ⁴²He is 28 MeV. If two deuterons are fused to form one ⁴²He then the energy released is:
A
23.6 MeV
B
25.8 MeV
C
26.4 MeV
D
28.2 MeV
Correct Answer
Option B
Detailed Explanation
The energy released in fusion is the difference in binding energies. Two deuterons have a total binding energy of 4.4 MeV, and ⁴²He has 28 MeV, so the energy released is 28 - 4.4 = 23.6 MeV.
