A capillary tube is taken from earth's surface to moon's surface. The rise of liquid column on the moon's surface is (acceleration due to gravity on the earth's surface is six times that of moon's surface)
Options
- Azero.
- Bsix times that on the earth's surface.
- Cequal to that on the earth's surface.
- D( 1 6 )^ th that on the earth's surface.
Correct answer
B. six times that on the earth's surface.
Step-by-step solution
The height of the liquid column is determined by the equation h = 2T g r , where g is the only variable when moving from Earth to the Moon. Given that g_E = 6g_M , we substitute g_M = g_E 6 into the height expression for the Moon: h_M = 2T (g_E/6) r = 6 2T g_E r = 6h_E . Therefore, the rise on the Moon is six times that on Earth, and the correct answer is B.
