  1. Question 1

    Q1. The mass defect of a nucleus is 0.01 u. What is the binding energy per nucleon if the nucleus has 20 nucleons?

    • A) 9.31 MeV
    • B) 4.65 MeV
    • C) 0.465 MeV
    • D) 46.5 MeV

    Answer: 0.465 MeV

    Explanation: Binding energy = 0.01 u × 931 MeV/u = 9.31 MeV. Per nucleon, it's 9.31/20 = 0.465 MeV. Other options miscalculate.
