The String is just taut, when the two spheres are completely in the liquid. If the density of the materials of the two spheres is $2800 \mathrm{kgm}^{-3}$, then the terminal velocity of the system of the sphere is (take $\mathrm{g}=10 \mathrm{~ms}^{-2}$ )

Assuming that the two liquids do not mix, the velocity with which the oil drop rises will depend on:
