Water $\left(\rho=1000 \,kg / m ^3\right)$ and kerosene $\left(\sigma=800 \,kg / m ^3\right)$ are filled in two identical cylindrical vessels. Both vessels have small holes at their bottom. The speed of the water and kerosene coming out of their holes are $v_1$ and $v_2$ respectively. Select the correct alternative

(a)
Velocity of efflux for small holes $=\sqrt{2 g h}$
Which clearly is independent of ' $\rho$ ' (density) So, $v_1=v_2$
