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 the Earth is 6 times that of the Moon) is

Options

A. six times that on the earth's surface
B. `(1)/(6)` that on the earth's surface
C. equal to that on the earth's surface
D. zero

Answer

A

Explanation

By the relation, `h = (2S cos theta)/(rdg)` and `(h_(2))/(h_(1)) = (g_(1))/(g_(2))`
`(h_(2))/(h) = (g)/(g//6) rArr h_(2) = 6h`
Hence, the rise of the liquid column on the moon becomes six times that on the earth's surface.
