There is an air bubble of radius 1.0 mm in a liquid of surface tension `0.075Nm^-1` and density `1000 kg m^-3`. The bubble is at a depth of 10 cm below the free surface. By what amount is the pressure inside the bubble greater than the atmospheric pressure? Take `g=9.8ms^-2`.

Explanation

To find the pressure inside the bubble greater than the atmospheric pressure, we can follow these steps:

### Step 1: Understand the Pressure at Depth
The pressure at a depth \( h \) in a fluid is given by the formula:
\[ P = P_0 + \rho g h \]
where:
