Water of density p in a clean aquarium forms a meniscus, as illustrated in the figure. Calculate the difference in height h between the centre and the edge of the meniscus. The surface tension of water is\[\gamma \].

• A. \[\sqrt{\frac{2\gamma }{\rho g}}\]
• B. \[\sqrt{\frac{\gamma }{\rho g}}\]
• C. \[\frac{1}{2}\sqrt{\frac{\gamma }{\rho g}}\]
• D. \[2\sqrt{\frac{\gamma }{\rho g}}\]
