The excess pressure inside a soap bubble of radius 6mm is balanced by 2mm column of all of density 800 `kgm^(-3)`. Find the surface tension of soap solution.

Explanation

To find the surface tension of the soap solution, we can follow these steps:

### Step 1: Understand the relationship between excess pressure and height of the liquid column
The excess pressure inside a soap bubble is given by the formula:
\[ \Delta P = \frac{4\sigma}{r} \]
where \( \sigma \) is the surface tension and \( r \) is the radius of the bubble.
