The energy equivalent of 1 g mass is MCQ with Answer and Explanation

The energy equivalent of 1 g mass is
A. 9×10¹⁰ J
B. 3×10⁸ J
C. 9×10¹³ J
D. 9×10¹⁶ J
Answer: Option C
Solution (By JKSSB Mock Tests)
E = mc² = 0.001 kg × (3×10⁸)² = 0.001 × 9×10¹⁶ = 9×10¹³ J. Enormous energy. 1 g mass if fully converted gives this. Atomic bomb converts small fraction.
