$The energy required to break one bond in DNA is 10^{- 20} J. This value (in eV) is nearly [NEET 2020]$

Topic: NEET PYQ

Answer: B. Full step-by-step solution below.

A $0.6$
B $0.06$
C $0.006$
D $6$

Correct answer: B

Solution

(b) Given, E = 10^{- 20} J In terms of eV, we get E = \frac{10 ^{- 20}}{1.6 \times 10 ^{- 19}} eV = 0.06 eV
