Question

Water rises to a height h in a capillary tube held vertically.in a beaker containing water. If the capillary tube is inclined at an angle ${30}^{\circ }$ with the water surface, the length to which water rises in the capillary will be.

• A. $\frac{h}{2}$
• B. $h$
• C. $\frac{2h}{\sqrt{3}}$
• D. $2h$

Answer 1

Answer: (D)

$2h$

$\text{Capaliry rise due to pressure}$

$\text{difference.}$

$\frac{H}{l}=\sin 30$

$l=2h$

$\text{Answer:-(D)}$
