Question

Water rises in a capillary tube through a height h. If the tube is inclined to the liquid surface at ${45}^{\circ }$, the liquid will rise in the tube up to its length equal to:

• A. $\frac{h}{\sqrt{2}}$
• B. $h$
• C. $\sqrt{2}h$
• D. $2h$

Answer 1

The correct option is C $\sqrt{2}h$

Capillary rise due to

pressure difference

So,

$\sin {45}^{\circ }=\frac{h}{l}$

$\frac{1}{\sqrt{2}}=\frac{h}{l}.$

$l=\sqrt{2}h$

Answer $:-\left(c\right)\sqrt{2}h$
