An air bubble of radius $\displaystyle 0.1$ cm is in a liquid having surface tension $\displaystyle 0.06 \mathrm{~N} / \mathrm{m}$ and density $\displaystyle 10^3 \mathrm{~kg} / \mathrm{m}^3$. The pressure inside the bubble is $\displaystyle 1100 \mathrm{Nm}^{-2}$ greater than the atmospheric pressure. At what depth is the bubble below the surface of the liquid ? $\displaystyle \left(\mathrm{g}=9.8 \mathrm{~ms}^{-2}\right)$
Official answer
(1)
