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 tha earth surface
C. equal on that of the earth surface
D. zero

Answer

A

Explanation

Rise of liquid in a capillary tube h=`(2c cos theta)/(rrhog)`
`hprop(1)/(g)`
`:. (h_("moon"))/(h_("earth"))=(g_("earth"))/(g_("moon"))=(6g_("moon"))/(g_("moon"))=6`
`h_("moon")=6h_("earth")`
