A) Internal pressure of the smaller bubble is higher than the internal pressure of the larger bubble
B) Pressure of the larger bubble is higher than the smaller bubble
C) Both bubbles have the same internal pressure
D) None of the above
Correct Answer: A
Solution :
\[\Delta \,P=\frac{4T}{R}\]\ \[\Delta P\propto \frac{1}{R}\] (T = constant) Hence, the internal pressure of smaller bubble is larger than that of larger bubble.
