Two large glass plates are placed vertically and parallel to each other inside a tank of water with separation between the plates equal to 1 mm. Find the rise of water in the space between the plates. Surface tension of water = 0.075 N m^-1.

Question

Philoid · Accepted Answer

1.5 cm

Here, consider a unit length in glass plates.

Given, surface tension of water,

Separation between the plates

The force is given by,

The weight of water in unit volume is

Thus,

Two large glass plates are placed vertically and parallel to each other inside a tank of water with separation between the plates equal to 1 mm. Find the rise of water in the space between the plates. Surface tension of water = 0.075 N m-1.
