Question

Water rises in a capillary tube through a height 'I'. 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 $\left(B\right)$ is correct answer.l
