Условие

A charged capacitor with capacitance $C$ is closed to an uncharged capacitance $3C$ and a resistor, which are connected in parallel. What percentage of the initial energy of the charged capacitor will be released on the resistor? The resistance of connecting wires is negligible.

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. $g = 10\ \mathrm{m/s^2}$.
