Solution

The correct option is A $1.6 \times 10^{- 17} J$
The definition of 1eV is:
It is the kinetic energy acquired by an electron which has been accelerated from rest in a potential difference of $1 V$ .
Thus, in this case, the kinetic energy of the electron will be $100 e V$
$= 1.6 \times 10^{- 19} \times 100$
$= 1.6 \times 10^{- 17} J$
