The diameter of an air bubble which was initially 2 mm, rises steadily through a solution of density 1750 kg m~ 3 at the rate of 0.35 cms -1 . The coefficient of viscosity of the solution is_______ poise (in nearest integer), (the density of air is negligible).
Text Solution
Verified by ExpertsThe correct answer is:
11
(11)
As the bubble is rising steadily the net force acting on it will be zero
(Because of density of air the value of mg can be neglected)
So 
Putting 
SI unit = 11 poise (CGS)
