Two isolated conducting spheres $\displaystyle S_1$ and $\displaystyle S_2$ of radius $\displaystyle \frac{2}{3} \mathrm{R}$ and $\displaystyle \frac{1}{3} \mathrm{R}$ have $\displaystyle 12 \mu \mathrm{C}$ and $\displaystyle -3 \mu \mathrm{C}$ charges, respectively, and are at a large distance from each other. They are now connected by a conducting wire. A long time after this is done the charges on $\displaystyle \mathrm{S}_1$ and $\displaystyle \mathrm{S}_2$ are respectively:
