A) Air from end 1 flows towards end 2. No change in the volume of the soap bubbles
B) Air from end 1 flows towards end 2. Volume of the soap bubble at end 1 decreases
C) No change occurs
D) Air from end 2 flows towards end 1. Volume of the soap bubble at end 1 increases
Correct Answer: B
Solution :
Pressure inside tube \[=P={{P}_{0}}\,+\,\frac{4T}{r}\] \[\therefore \,\,\text{ }{{P}_{2}}<{{P}_{1}}\] (since \[{{r}_{2}}>{{r}_{1}}\]) Hence pressure on side 1 will be greater than side 2. So air from end 1 flows towards end 2.You need to login to perform this action.
