    Q1. A photon collides with a stationary electron. What is the minimum energy required for pair production?

    • A) 0.51 MeV
    • B) 1.02 MeV
    • C) 1.5 MeV
    • D) 2.04 MeV

    Answer: 1.02 MeV

    Explanation: Minimum energy = 2 × rest mass energy of electron = 2 × 0.51 MeV = 1.02 MeV. Other options are incorrect or miscalculated.
