SATHEE: Atoms And Nuclei Question 258

Atoms And Nuclei Question 258

Question: If in a nuclear fission, piece of uranium of mass 0.5 g is lost, the energy obtained in kWh is [Pb. PET 2003]

Options:

A) $1.25 \times 10^{7}$

B) $2.25 \times 10^{7}$

C) $3.25 \times 10^{7}$

D) $0.25 \times 10^{7}$

Show Answer

Answer:

Correct Answer: A

Solution:

$E = Δ m c^{2} = 0.5 \times 10^{- 3} \times {(3 \times 10^{8})}^{2} = 4.5 \times 10^{13} j$
$\Rightarrow E = \frac{4.5 \times 10^{13}}{3.6 \times 10^{6}} = 1.25 \times 10^{7} k W H .$
