what will happen to capillary rise effect if we take capillary to space g=0?

Capillary rise effect is the phenomenon where a liquid is drawn upwards against gravity due to the attractive forces between the liquid molecules and the surface of a solid material, such as a narrow tube or pore.
The smaller the capillary size, the higher the capillary rise. This is because smaller capillaries have a larger surface area per unit volume, which increases the attractive forces between the liquid and the capillary walls.
The capillary rise effect is influenced by the surface tension of the liquid, the density of the liquid, the diameter of the capillary, and the angle of contact between the liquid and the capillary walls.
The capillary rise effect decreases with increasing altitude. This is because at higher altitudes, the atmospheric pressure decreases, resulting in a decrease in the pressure difference between the top and bottom of the capillary, which is necessary for the capillary rise effect to occur.
Yes, the capillary rise effect can be reversed by applying an external force, such as gravity or centrifugal force, that overcomes the attractive forces between the liquid and the capillary walls. This is known as the capillary depression effect.
