Question : 12

Total: 42

The pressure at any point in a liquid at rest depends only on the

Solution:

Concept:

Pressure in a static liquid is given by

P = \rho g h

Explanation:

At a point in a liquid at rest, pressure depends on:

• the depth

h

below the liquid surface,

• the density

\rho

of the liquid,

• the acceleration due to gravity

g

It does not depend on the mass, volume, surface area, or viscosity of the liquid.

Answer:

A. depth and the density
