This question is in two parts

Ionized hydrogen atoms are accelerated from rest in the vacuum between two vertical parallel conducting plates. The potential difference between the plates is V. As a result of the acceleration each ion gains an energy of $1.9 \times 10^{-18} \mathrm{~J}$ .

Calculate the value of V.

$\quad V=\frac{1.9 \times 10^{-18}}{1.6 \times 10^{-19}}$ ;
$=12 \mathrm{~V}$ ;
