JEE Main 2017 Physics question
Two deuterons undergo nuclear fusion to form a Helium nucleus. The energy released in this process is (given binding energy per nucleon for deuteron MeV and for helium MeV):
Answer: (1)
Solution
The reaction is
^\mathrm H + {}^\mathrm H He.
The energy released equals the increase in total binding energy, since a more tightly bound product releases the difference. **Reactants:** each deuteron has nucleons at MeV per nucleon, so MeV in
