  1. Question 1

    Q1. In a fission reaction, 0.001 kg of mass is converted to energy. How much energy is released? (c = 3 × 10⁸ m/s)

    • A) 9 × 10¹³ J
    • B) 9 × 10¹⁴ J
    • C) 9 × 10¹² J
    • D) 9 × 10¹¹ J

    Answer: 9 × 10¹³ J

    Explanation: E = mc² = 0.001 × (3 × 10⁸)² = 9 × 10¹³ J. Option B misplaces the decimal.
