Question

In gravity free space, the liquid in capillary tube will rise to
A. The same height as in earth
B. Less height as on earth
C. Slightly more height than that on earth
D. Top and overflow

Answer 1

Hint
As we know that if gravity is not available on the earth then we can't walk over the ground, can't do our daily works, and the earth is not looking the same as it is now. So think what will happen with the liquid present in a capillary tube.

Complete step by step answer
First of all, we will understand that what is gravitational force and surface tension are acting on the liquid present in the capillary tube.
Gravity: gravity is a universal force, which attracts all matters present in the universe. Gravity is also known as gravitational force. It is the weakest known force in nature, but it controls the trajectories of bodies in the solar system. On earth, gravity gives weight to physical objects.
Surface tension: the surface area is a tendency of a liquid to shrink in a minimum area. Because of the surface tension, a small drop of liquid or soap bubble has a nearly spherical shape.
In space where gravity is zero, the weight of liquid will also be zero as we know that weight of a body is equal to the product of the mass of the body and gravity, and zero gravity will make weight zero. When gravitational force is zero then no force can balance the surface tension of the liquid so surface tension will pull the liquid in an upward direction to top level and overflow.
Option (D) is the right option.

Note
The point to be noted in this question is we should know that in a capillary tube liquid will be balanced due to gravitational force and surface tension, and if gravitational force will be zero then the liquid present in the capillary tube will definitely get in imbalance.
