In a surface tension experiment with a capillary tube water rises upto `0.1m`. If the same experiment is repeated in an artificial satellite, which is revolving around the earth, water will rise in the capillary tube upto a height of

Options

A. `0.1m`
B. `0.2m`
C. `0.98m`
D. Full length of tube

Answer

D

Explanation

Under normal condition, upward surface tension force supports the weight of liquid of height h is the capillary. In artificial satellite effective weight will be zero, but upward surface tension force will be there. Hence, liquid rises upto the top.
