Two isolated conducting spheres $S_{1}$ and $S_{2}$ of radius $\frac{2}{3} R$ and $\frac{1}{3} R$ have $12\, \mu C$ and $-3\, \mu C$ charges, respectively, and are at a large distance from each other. They are now onnected by a conducting wire. A long time after this is done the charges on $S_{1}$ and $S_{2}$ are respectively
