Question

Water rises in a capillary tube through a height $l$. If the tube is inclined to the liquid surface at ${30}^{\circ }$ , the liquid will rise in the tube upto it's length equal to

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

Answer 1

The correct option is B $2l$

length will be $2l$

So, that height is $2lsin{30}^0=l$

Hence,

option $B$ is correct answer.
