A) becomes concave towards A
B) becomes convex towards A
C) either (a) or (b) depending on the size of A with respect to B
D) remains in the initial position
Correct Answer: C
Solution :
The air pressure inside a soap bubble is \[P=\frac{4T}{R}\]which is greater than the atmospheric pressure. If a hole is made at A, air will flow outside through A. Then the thread becomes convex looking from A and from B towards A it is concave. Hence, becoming concave or convex, depends on the size of A with respect to B.You need to login to perform this action.
