Problem

Consider two solid spheres PP and QQ each of density 8 gm cm−38\,\mathrm{gm\,cm^{-3}} and diameters 1 cm and 0.5 cm, respectively. Sphere PP is dropped into a liquid of density 0.8 gm cm−30.8\,\mathrm{gm\,cm^{-3}} and viscosity η=3\eta=3 poiseulles. Sphere QQ is dropped into a liquid of density 1.6 gm cm−31.6\,\mathrm{gm\,cm^{-3}} and viscosity η=2\eta=2 poiseulles. The ratio of the terminal velocities of PP and QQ is
