A capacitor $\displaystyle C$ is fully charged with voltage $\displaystyle \mathrm{V}_0$. After disconnecting the voltage source, it is connected in parallel with another uncharged capacitor of capacitance $\displaystyle \frac{\mathrm{C}}{2}$. The energy loss in the process after the charge is distributed between the two capacitors is :
