Water of density $ρ$ 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 $γ$ .

Options:

Answer:

Solution:

$F_{s u r f a ce} = γ$

$F_{p ress u re} = \int_{0}^{h} ρ g y d y = \frac{1}{2} ρ g h^{2}$

$γ = \frac{1}{2} ρ g h^{2}$

$h^{2} = \frac{2 γ}{ρ g}$

$h = \frac{2 γ}{ρ g}$
