Question

The pressure at depth below the surface of a liquid of density $\rho$ open to the atmosphere is

A

Greater than the atmospheric pressure by

B

Less than the atmospheric pressure by

C

Equal to the atmospheric pressure

D

Increases exponentially with depth

Answer

Greater than the atmospheric pressure by

Explanation

Solution

The pressure at depth h below the surface of a liquid of density $\rho$ open to the atmosphere is

Where is the atmospheric pressure

Thus, pressure P at depth h below the surface of a liquid open to the atmosphere is greater than the atmospheric pressure by an amount
