A $2\, \mu F$ capacitor $C _{1}$ is first charged to a potential difference of $10\, V$ using a battery.Then the battery is removed and the capacitor is connected to an uncharged capacitor $C _{2}$ of $8\, \mu F$. The charge in $C _{2}$ on equilibrium condition is $\ldots\,\mu C$. (Round off to the Nearest Integer)
