Question

Water rises in a capillary tube through a height h. If the tube is inclined to the liquid surface at 45°, the liquid will rise in the tube upto its length equal to ______.

Options

• h/`sqrt2`

• h

• `sqrt2` h

• 2 h

Answer 1

Water rises in a capillary tube through a height h. If the tube is inclined to the liquid surface at 45°, the liquid will rise in the tube upto its length equal to `bbunderline(sqrt2  "h")`.

Explanation:

In a capillary tube vertical height of rise would remain same.

h cos 45° = h

h = h`sqrt2`
