Choose an option
Show full solutionCorrect option: B
Correct answer
B
Step-by-step explanation
The fusion reaction is given by:
Binding energy of one nucleus = MeV
Total initial binding energy = MeV
Binding energy of nucleus = MeV
Energy released = Final binding energy - Initial binding energy
MeV
Answer:
Binding energy of one nucleus = MeV
Total initial binding energy = MeV
Binding energy of nucleus = MeV
Energy released = Final binding energy - Initial binding energy
MeV
