Angle of Contact & Capillarity question from MHT CET 2021 (21 Sep, Shift 2)

Answer: (a)

1. $h \propto \frac{1}{g}$; a much larger rise needs a much smaller $g$.
2. At the poles $g$ is slightly larger, at the equator only slightly smaller, and in a lift going up $g_{\text{eff}} = g + a$ is larger.
3. On the moon $g$ is about $\frac{g}{6}$, so $h \approx 60\text{ cm}$.
4. So the answer is (a) on the surface of the moon.
