Answer 1

If a capillary tube is dipped in water in a state of weightlessness, then water will rise to the maximum available height of the tube.

Explanation:

The effective weight on the water column raised in the tube will be zero in a condition of weightlessness. As a result, water will rise to the capillary's opposite end.

Regardless of how long the capillary is.
