When $_{92} U^{235}$ undergoes fission. 0.1% of its original mass is changed into energy. $9 \times 10^{x} J$ of energy is released if $1 k g$ of $_{92} U^{235}$ undergoes fission. Value of $x$ = ___

Q. An explosion of atomic bomb releases

Sikar read that when 92U235 undergoes fission, approximately 0.1% of its original mass changes into energy. With this information, calculate the amount of energy released when 1kg of 92U235 undergoes fission.[Use the mass-energy equivalence]

The correct option is A 9×1013JΔm=0.1100×1 kg=10−3 kg1 kg=9×1016 J.10−3 kg=9×1016×10−3 J=9×1013 J

[Use the mass-energy equivalence]

The correct option is A $9 \times 10^{13} J$
$\begin{matrix} Δ m & = \frac{0.1}{100} \times 1 k g = 10^{- 3} k g 1 k g & = 9 \times 10^{16} J . 10^{- 3} k g & = 9 \times 10^{16} \times 10^{- 3} J = 9 \times 10^{13} J \end{matrix}$
