Question:medium
A soap bubble of radius \( R \) is surrounded by another soap bubble of radius \( 2R \) as shown in figure. The excess pressure inside the smaller soap bubble will be (\( T \) = surface tension of soap solution)
A soap bubble of radius \( R \) is surrounded by another soap bubble of radius \( 2R \) as shown in figure. The excess pressure inside the smaller soap bubble will be (\( T \) = surface tension of soap solution)
Show Hint
- Soap bubble: $\Delta P = \frac{4T}{r}$
- Always consider surrounding pressure medium carefully
Updated On: May 4, 2026
- \( \frac{3T}{2R} \)
- \( \frac{3T}{R} \)
- \( \frac{4T}{R} \)
- \( \frac{6T}{R} \)
Show Solution
The Correct Option is B
