A small drop of water falls from rest through a large height $h$ in air; the final velocity is ................

A

Proportional to $\sqrt{h}$

B

Proportional to $h$

C

Inversely proportional to $h$

D

Almost independent of $h$

Solution

(d)

Since drop is falling from a large height it achieves its terminal velocity and then there is no further increase in velocity so $v$ is independent of ' $h$ ' if ' $h$ ' is very large.
