If a ball of steel (density rhos=7.8 g/cm3) attains a terminal velocity of 10 cm/s when falling in a tank of water (coefficient of viscosity, ηw=8.5×10−4 Pa-s). Then, its terminal velocity in glycerine (rhog=1.2 g/cm3,ηg=13.2 Pa-s) would be nearly:
A 1.6×10⁻⁵ cm/s
B 1.5×10⁻⁵ cm/s
C 6.45×10⁻⁴ cm/s
D 6.25×10⁻⁴ cm/s
