Units & Dimensions

The energy required to break one bond in DNA is 10-20 J. This value in eV is nearly:

Show answer and solution

Answer: (b)

The energy is $10^{-20}\text{ J}$ and $1\text{ eV} = 1.6 \times 10^{-19}\text{ J}$ .
$E = \frac{10^{-20}}{1.6 \times 10^{-19}}\text{ eV} = 0.0625\text{ eV}$
So the answer is (b) $0.06$ .
