Angle of Contact & Capillarity

Water rises to a height $3$ cm in a capillary tube. If cross-sectional area of capillary tube is reduced to $1/3^{rd}$ of its initial area then water will rise to a height of

Show answer and solution

Answer: (a)

$h \propto \frac{1}{r} \propto \frac{1}{\sqrt{A}}$
$A' = \frac{A}{3} \Rightarrow h' = h\sqrt{3} = 3\sqrt{3}\text{ cm}$
So the answer is (a) $3\sqrt{3}$ cm.
