If a ball of steel (density p=7.8g cm-3) attains a terminal velocity of 10cm s-1 when falling in water (Coefficient of viscosity ?water = 8.5*10-4 Pa.s), then, itsterminal velocity in glycerine (p=1.2g cm-3, ?=13.2 Pa.s) would be, nearly(a) 6.25 * 10-4 cm s-1(b) 6.45 *10-4 cm s-1(c) 1.5 * 10-5cm s-1(d) 1.6 * 10-5cm s-1
