The height of liquid column raised in a capillary tube of certain radius when dipped in liquid A vertically is, \(5 cm\). If the tube is dipped in a similar manner in another liquid \(B\) of surface tension and density double the values of liquid \(A\), the height of liquid column raised in liquid \(B\) would be \(........m\).

Answer & Solution

Correct Answer

(C) \(0.05\)

Step-by-step Solution

Detailed explanation

\(h =\frac{2 S \cos \theta}{ r \rho g }\)

\(\frac{ h _1}{ h _2}=\frac{ S _1}{ S _2} \frac{\rho_2}{\rho_1}\)

\(\frac{5}{ h _2}=\left[\frac{1}{2}\right]\left[\frac{2}{1}\right] \Rightarrow h _2=5\,cm =0.05\,m\)
