If two soap bubbles of different radii are in communication with each other
Text Solution
Verified by ExpertsThe correct answer is:
C
Excess of pressure in a soap bubble 
where T is surface tension of soap solution and
is the radius of die bubble.
Therefore, pressure is greater in soap bubble of smaller radius.
Hence, air will flow from the smaller bubble into the larger bubble and the larger bubble grows at the expense of the smaller one.
