Two soap bubbles of different radii `r_(1)andr_(2)` are in contact. Determine the radius of the interface.

Text Solution

AI Generated Solution

To determine the radius of the interface between two soap bubbles of different radii \( r_1 \) and \( r_2 \), we can follow these steps: ### Step 1: Understand the concept of excess pressure in soap bubbles The excess pressure inside a soap bubble is given by the formula: \[ P = \frac{4\sigma}{r} \] where \( P \) is the excess pressure, \( \sigma \) is the surface tension of the soap solution, and \( r \) is the radius of the bubble. ...
