# Q1 of 180

Consider a water tank shown in the figure. It has one wall at x = L and can be taken to be very wide in the z direction. When filled with a liquid of surface tension S and density ρ, the liquid surface makes angle θ₀ (θ₀ << 1) with the x-axis at x = L. If y(x) is the height of the surface then the equation for y(x) is:

$(take θ (x) = \sin θ (x) = \tan θ (x) = \frac{d y}{d x}, g is the acceleration due to gravity)$

Options :

$\frac{d^{2}}{d x^{2}} y = \frac{ρ g}{S} x$

$\frac{d^{2}}{d x^{2}} y = \frac{ρ g}{S} y$

$\frac{d^{2}}{d x^{2}} y = \sqrt{\frac{ρ g}{S}}$

$\frac{dy}{dx} = \sqrt{\frac{ρ g}{S}} x$
