1.	An air bubble of radius 10^-2 m is rising up at a steady rate2×103
Answer» bubble of 1cm radius is rising at a steady rate of 2 through a liquid of DENSITY 1.5 3 NEGLECT density of air, if g is 1000 2 , then the coefficient of viscosity of the liquid is ? Force of viscosity equals (Stokes' law): = 6 where – speed of the bubble, - coefficient of viscosity Buoyant force that is exerted on bubble equals: = = 4 3 3 NEWTON’s first law of MOTION: = 6 = 4 3 3 = 4 3 3 6 = 2 2 9 ≅ 167 ∗
