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:
CHECK THE SOLUTION.
(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)
