One MeV of nuclear energy is equivalent to:(a) 1.6 × 10^−13J (b) 1.6 × 10^−19J (c) 1.6 × 10^−16J (d) 1.6 × 10^−15J

 (a) 1.6 × 10^−13 J

Explanation

One eV (electron volt) of nuclear energy is equivalent to 1.6 × 10−19 Joule, which is the amount of energy acquired by an electron having a charge of 1.6 × 10−19 Coulomb when accelerated through a potential difference of 1 volt. 

We know that,

1 eV = 1000 MeV

Then, 1.6 × 10^−19J = 1000 MeV  $(\because $ 1eV = 1.6 × 10^−19 J )

So, $1MeV=\frac{1.6\times {10}^{-19}}{1000}$

1 meV =  1.6 × 10^−13 J
