A wide vessel with small hole in the bottom is filled with water and kerosene. Neglecting viscosity, the velocity of water flow v, if the thickness of water layer is h1 and that of kerosene layer is h2 is (density of water \mathrm{\rho 1 \mathrm{gm} / \mathrm{cc}} and that of kerosene is \mathrm{\rho 2 \mathrm{gm} / \mathrm{cc}.}

Option: 1

\mathrm{v=\sqrt{2 g\left(h_1+h_2\right)}}


Option: 2

\mathrm{v=\sqrt{2 g\left(h_1 \rho_1+h_2 \rho_2\right)}}


Option: 3

\mathrm{v=\sqrt{2 g\left[h_1+h_2\left(\frac{\rho_2}{\rho_1}\right)\right]}}


Option: 4

\mathrm{v=\sqrt{2 g\left[h_1\left(\frac{\rho_1}{\rho_2}\right)+h_2\right]}}
