SATHEE: Atoms And Nuclei Question 191

Atoms And Nuclei Question 191

Question: The mass defect in a particular nuclear reaction is 0.3 grams. The amount of energy liberated in kilowatt hours is (Velocity of light = $3 \times 10^{8}, m / s$ ) [EAMCET 2003]

Options:

A) $1.5 \times 10^{6}$

B) $2.5 \times 10^{6}$

C) $3 \times 10^{6}$

D) $7.5 \times 10^{6}$

Show Answer

Answer:

Correct Answer: D

Solution:

$E = Δ m . c^{2}$
$\Rightarrow E = \frac{0.3}{1000} \times {(3 \times 10^{8})}^{2} = 2.7 \times 10^{13} J$ $= \frac{2.7 \times 10^{13}}{3.6 \times 10^{6}} = 7.5 \times 10^{6} k W h$ .
