Question

A cylinder is filled with a liquid of density 'd' upto height h. If the beaker is at rest, then the mean pressure on the wall.

Answer 1

the pressure will be. dgh

Answer 2

Answer:

It should be dgh/2.

Explanation:

Total mass is of the liquid is concentrated at its centre of mass.

For liquid of height h, CM would be at h/2.

Now mass of liquid = d×V= d×A×h/2.

Pressure = force/ A

.: P= h/2 dg
