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

Options

A. greater than the atmospheric pressure by `rhogh`
B. less than the atmospheric pressure by `rhogh`
C. equal to the atmospheric pressure
D. decreases exponentially with depth

Answer

A

Explanation

Pressure at depth h to the open surface
`p=p_(0)+hrhog`
i.e., the pressure at depth h below the surface of a liquid of density `rho` open to the atmosphere is greater than the atmosphere pressure by `rhogh`.
