There is an air bubble of radius $\displaystyle 1.0$ mm in a liquid of surface tension $\displaystyle 0.075 \mathrm{Nm}^{-1}$ and density $\displaystyle 1000 \mathrm{~kg} \mathrm{~m}^{-3}$ at a depth of $\displaystyle 10$ cm below the free surface. The amount by which the pressure inside the bubble is greater than the atmospheric pressure is $\displaystyle \_\_\_\_$ $\displaystyle P a\left(g=10 \mathrm{~ms}^{-2}\right)$
