Mechanical Properties of Fluids

Question: A streamlined body falls through air from a height h on the surface of a liquid. If d and D(D > d) represents the densities of the material of the body and liquid respectively, then the time after which the body will be instantaneously at rest, is

1) $\sqrt{\frac{2h}{g}}$

2) $\sqrt{\frac{2h}{g}\,.\,\frac{D}{d}}$

3) $\sqrt{\frac{2h}{g}\,.\,\frac{d}{D}}$

4) $\sqrt{\frac{2h}{g}}\,\left( \frac{d}{D-d} \right)$
