An air bubble of diameter 2 mm rises steadily through a solution of density 1750 kg/m at the rate of 0.35 cm/sec. What is the viscosity of the solution? (A) 1 Poise (B) 11 Poise (C) 110 Poise (D) 50 Poise
in this question, density of air bubble is not given.. u can use the formula Viscosity = (2 x ( density of air bubble – liquid density) x g x r^2) ÷ (9 x v), where g = acceleratio...
