Water can rise up to a height of 10 cm in a capillary tube. If a capillary of same diameter but of length 6 cm is held vertically in water, will the water come out in the form of a fountain? Explain.

Explanation

No, when the size of the capillary is less than the height to which the water can rise, the radius of curvature of water meniscus adjusts itself so that there is no over flowing of water but the product of height of liquid and radius of curvature of the meniscus remains a finite constant.
