Two deuterons undergo nuclear fusion to form a Helium nucleus. Energy released in this process is (given binding energy per nucleon for deuteron =1.1 MeV and for helium =7.0 MeV)

Asked in JEE Main Online 2017 · Energy released in fission and fusion

• (1) 25.8 MeV
• (2) 32.4 MeV
• (3) 30.2 MeV
• (4) 23.6 MeV

Step-by-step solution

Why the other options are wrong

• (1) Subtracts only one deuteron.
• (2) Adds instead of subtracting.
• (3) Adds one deuteron binding energy instead of subtracting both.
