A capillary tube is placed vertically in water and water rises to height h above the surface of water in the capillary tube. If the tube is inclined with vertical at angle θ, then it rises to height t. Find t.

Given, a capillary tube is placed in water and water rises to a height h above the surface of water in the capillary tube.

The vertical height to which the liquid rises in the capillary tube remains constant as shown.

From the figure, we have

h/ t = cos θ
⇒ t = h cos  [∵ cos θ < 1]

∴  t > h

What is hydrostatics?

Hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest. The study of fluids at rest or objects placed at rest in fluids is hydrostatics.

Why solids have definite shape while liquids do not have definite shape?

Solids: Intermolecular forces are very strong and thermal agitations are not sufficiently strong to separate the molecules from their mean position. Solids are rigid and hence they have definite shapes.
Liquids: In liquids intermolecular forces are not sufficiently strong to hold the molecules at definite sites, as a result they move freely within the bulk of liquid, therefore, do not possess definite shapes. Liquids take the same shape as that of the container.
