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 `H_(1)` and that of kerosene layer is `H_(2)` is (density of water `rho_(1)//cc` and that of kerosene is `rho_(2)//cc`.

Options

A. `[2g(h_(1)+h_(2))]^(1//2)`
B. `[2g(h_(1)rho_(1)+h_(2)rho_(2))]^(1//2)`
C. `[2g(h_(1)+h_(2)(rho_(2)//rho_(1)))]^(1//2)`
D. `[2g(h_(1)+h_(2)(rho_(1)//rho_(2)))]^(1//2)`
