Water rises to a height fo 6 cm in a capillary tube of radius r . If the radius of the capillary tube is 3r, the height to which water will rise is ….cm.

Assertion : The water rises higher in a capillary tube of small diameter than in the capillary tube of large diameter. Reason : Height through which liquid rises in a capillary tube is inversely proportional to the diameter of the capillary tube.

A capillary tube of radius r is immersed in water and water rises in to a height h. The mass of water in the capillary tube is 5g. Another capillary tube of radius 2 r is immersed in water. The mass of water that will rise in this tube is

Water rises in a capillary tube to a height H , when the capillary tube is vertical. If the same capillary is now inclined to the vertical the length of water column in it will
