Atoms And Nuclei Question 209

Question: When $_{92} U^{235}$ undergoes fission, 0.1% of its original mass is changed into energy. How much energy is released if 1kg of $_{92} U^{235}$ undergoes fission [MP PET 1994; MP PMT/PET 1998; BHU 2001; BVP 2003]

Options:

A) $9 \times 10^{10} J$

B) $9 \times 10^{11} J$

C) $9 \times 10^{12} J$

D) $9 \times 10^{13} J$

Show Answer

Answer:

Correct Answer: D

Solution:

$E = Δ m c^{2}, Δ m = \frac{0.1}{100} = 10^{- 3} k g$
$∴ E = 10^{- 3} \times {(3 \times 10^{8})}^{2} = 10^{- 3} \times 9 \times 10^{16} = 9 \times 10^{13} J$ .
