A bubble having surface tension T and radius R is formed on a ring of radius `b(b lt lt R)`. Air is blown inside the tube with velocity v as shown. The air molecule collides perpendicularly with the wall of the bubble and stops. Calculate the radius at which the bubble separates from the ring.

Text Solution

Verified by Experts
