Angle of Contact & Capillarity

A capillary tube is taken from the earth to the surface of the moon. The rise of the liquid column on the moon (acceleration due to gravity on earth is $6$ times that of the moon) is

Show answer and solution

Answer: (a)

$h = \frac{2T\cos\theta}{r\rho g}$ , so $h \propto \frac{1}{g}$ .
$g_{\text{moon}} = \frac{g}{6} \Rightarrow h_{\text{moon}} = 6h$ (tube long enough).
So the answer is (a) 6 times that of earth's surface.
