0.04 cm liquid column balances the excess pressure inside a soap bubble of radius 6 mm. Evaluate density of the liquid. Surface tension of soap solurtion =`0.03 Nm^(-1)`.

Explanation

To solve the problem, we need to evaluate the density of the liquid that balances the excess pressure inside a soap bubble. Here are the steps to arrive at the solution:

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