  1. Question 1

    Q1. The mass defect of a nucleus is 0.1 u. What is its binding energy?

    • A) 93 MeV
    • B) 93.1 MeV
    • C) 9.3 MeV
    • D) 931 MeV

    Answer: 93 MeV

    Explanation: Binding energy = mass defect * 931 MeV/u = 0.1 u * 931 MeV/u = 93.1 MeV. Option 'C' forgets to multiply by 931.
