An air bubble of diameter 6 mm rises steadily through a solution of density 1750 kg m -3 at the rate of 0. 35 cm s -1 . The co-efficient of viscosity of the solution (neglect density of air) is________Pas (given, g = 10 m s -2 ).
Text Solution
Verified by ExpertsThe correct answer is:
10
(10)
The bubble is moving with a constant velocity so the net force acting on the body is zero.
Stokes' law defines the drag force which is given by 
The buoyant force is given by 
Hence, it can be written that
