The adjoining diagram shows three soap bubbles A, B and C prepared by blowing the capillary tube fitted with stop cocks, S 1 , S 2 and S 3 . With stop cock S closed and stop cocks S 1 , S 2 and S 3 opened
Text Solution
Verified by ExpertsThe correct answer is:
C
Excess pressure inside soap bubble is inversely proportional to the radius of bubble i.e. 
This means that bubbles A and C posses greater pressure inside it than B. So the air will move from A and C towards B.
