Question

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 ______$m$

• A. $0.20$
• B. $0.5$
• C. $0.10$
• D. $0.05$

Answer 1

Answer: (D)

$0.05$

Answer 2

h=rρg2Scosθ​
∴h2​h1​​=S2​S1​​ρ1​ρ2​​
h2​5​=[21​][12​]⇒h2​=5cm=0.05m
{Info about angle of contact not there so most appropriate is 3 }
