The correct answer is:
$1.492 \times 10^{-10} \mathrm{~J}$
$\quad 1 \mathrm{u}=1.66 \times 10^{-24} \mathrm{~g}$
$=1.66 \times 10^{-27} \mathrm{~kg}$
$$
=1.66 \times 10^{-27} \times\left(3 \times 10^{8}\right)^{2} \mathrm{~kg} \mathrm{~m}^{2} \mathrm{~s}^{-2}\left(\because E=m c^{2}\right)
$$
$=1.494 \times 10^{-10} \mathrm{~J}$
$=1.66 \times 10^{-27} \mathrm{~kg}$
$$
=1.66 \times 10^{-27} \times\left(3 \times 10^{8}\right)^{2} \mathrm{~kg} \mathrm{~m}^{2} \mathrm{~s}^{-2}\left(\because E=m c^{2}\right)
$$
$=1.494 \times 10^{-10} \mathrm{~J}$
