When 92U23592U^{235}undergoes fission. 0.1% of its original mass is changed into energy. How much energy is released if 1 kg of 92U23592U^{235} undergoes fission

A

9 × 1010J

B

9 × 1011J

C

9 × 1012J

D

9 × 1013J

Answer

9 × 1013J

Explanation

Solution

By using E=Δmc2E = \Delta m \cdot c^{2}

E=(0.1100×1)(3×108)2=9×1013JE = \left( \frac{0.1}{100} \times 1 \right)(3 \times 10^{8})^{2} = 9 \times 10^{13}J
