There is an air bubble of radius 1. 0 mm in a liquid of surface tension 0. 075 N m -1 and density 1000 kg m -3 at a depth of 10 cm below the free surface. The amount by which the pressure inside the bubble is greater than the atmospheric pressure is_______Pa(g = 10 m s -2 ).
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(1150)
The pressure inside the bubble is given by
The data given is
r = 10 -3 m
T = 0. 075 N m -1
p = 1000 kg m -3
h = 10 cm
Therefore, the pressure in the bubble is
