Atoms And Nuclei Question 346

Question: 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)

Options:

A) 30.2 MeV

B) 32.4 MeV

C) 23.6 MeV

D) 25.8 MeV

Show Answer

Answer:

Correct Answer: C

Solution:

  • 1H2+1H22He4

    Total binding energy of two deuterium nuclei =1.1×4=4.4,MeV Binding energy of a 2He4

    nuclei =4×7=28MeV

    Energy released in this process =284.4=23.6MeV
