OLYMPIAD OF METROPOLISES. Moscow, September 4 · 4 септември 2017 г.

Условие

The electric potential at a point $X$ some distance away from a point charge $C$ is 2 V. The distance between points $Y$ and $C$ is a quarter of the distance between $X$ and $C$. Determine the work done when a test charge equivalent to that of 3 protons moves from the point $X$ to the point $Y$. Express the answer in electronvolts.

The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal.
$g = 10\ \mathrm{m/s^2}$.
