A soap bubble, having radius of $\displaystyle 1$ mm, is blown from a detergent solution having a surface tension of $\displaystyle 2.5 \times 10^{-2} \mathrm{~N} / \mathrm{m}$. The pressure inside the bubble equals at a point $\displaystyle \mathrm{Z}_0$ below the free surface of water in a container. Taking $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$, density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$, the value of $\displaystyle \mathrm{Z}_0$ is :
