Question

A liquid in a capillary, rises up to a height $h$ when the capillary is vertical. If the capillary is inclined at angle ${45}^{\circ }$ with the vertical, then the length of liquid in capillary will be

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

Answer 1

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

In a capillary tube vertical height of rise would remain same.

$h^{{}^{\prime }}\cos {45}^{\circ }=h$

$h^{{}^{\prime }}=h\sqrt{2}$
