(A) The height $h$ of a liquid column in a capillary tube is given by the formula:$h = \frac{2T \cos 	heta}{ho g r}$where $T$ is the surface tension,$	heta$ is the angle of contact,$ho$ is the density of the liquid,$g$ is the acceleration due to gravity,and $r$ is the radius of the capillary tube.Given that the angle of contact $	heta = 90^{\circ}$,we substitute this into the formula:$h = \frac{2T \cos 90^{\circ}}{ho g r}$Since $\cos 90^{\circ} = 0$,we get:$h = 0$Therefore,the liquid will neither rise nor fall in the capillary tube.

$A$ capillary tube stands with its lower end dipped into a liquid for which the angle of contact is $90^{\circ}$. The liquid will
