Question

One eV (electron volt) of nuclear energy is equivalent to :; A. 1.6 X 10-14 J; B. 1.6 X 10-12 J; C. 1.6 X 10-19 J; D. 1.6 X 10-13 J

Answer 1

Answer:

c.1.6x10^-19 is the correct answer

Answer 2

Answer:

(C)  $1.6\times 10^{-19}\ Joules$.

Explanation:

In the question,

1 eV is the amount of nuclear energy which is acquired or lost by an electron when it travels from the potential difference of 1 Volt.

It is a very small amount of energy generated by an electron.

1 eV = e x 1V

As we know,

KE = qV

So,

$KE=1.6\times 10^{-19}\ Joules$

Therefore, the value of 1 eV is equal to the $1.6\times 10^{-19}\ Joules$.

Hence, the correct option is (C).
