Angle of Contact & Capillarity

In a capillary tube of area of cross-section ' $a$ ' water rises to height ' $h$ '. To what height will water rise in a capillary tube of area of cross-section $4a$ ?

Show answer and solution

Answer: (b)

$h \propto \frac{1}{r}$ , $A = \pi r^2$ . Area $4a \Rightarrow$ radius doubles.
$h' = \frac{h}{2}$
So the answer is (b) $\frac{h}{2}$ .
