A body is projected vertically upwards. The times taken to reach height $h$ while ascending and descending are $t_1$ and $t_2$ respectively. Then, the velocity of projection is (where $g$ is the acceleration due to gravity).

Question

$g\left(\sqrt{t_1 t_2}\right)$

$g \frac{t_1 t_2}{t_1 + t_2} $

$g \frac{\sqrt{t_1 t_2}}{2} $

$g\left(\frac{t_1 + t_2}{2}\right) $
