    Two metal spheres are falling through a liquid of density 2.5×1032.5 \times 10^3 kg/m3^3 with the same uniform speed. The density of material of first sphere and second sphere is 11.5×10311.5 \times 10^3 kg/m3^3 and 8.5×1038.5 \times 10^3 kg/m3^3 respectively. The ratio of the radius of first sphere to that of second sphere is
