MCQ
A container of large uniform cross-sectional area $A$ is resting on a horizontal surface holds two immiscible, non-viscous and incompressible liquids of densities $d$ and $2d$ each of height $\frac{H}{2}$ as shown. The lower density of liquid is open to atmosphere. A small hole is made on the wall of container at height $h\left( {h < \frac{H}{2}} \right)$. The initial speed of efflux of the liquid at the hole is
- A$\left( {3H - 4h} \right)g$
- B$\frac{{\left( {3H - 4h} \right)g}}{2}$
- C$\sqrt {\left( {3H - 4h} \right)g} $
- ✓$\sqrt {\frac{{\left( {3H - 4h} \right)g}}{2}} $
