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

A

greater than the atmospheric pressure by `rhogh`

B

less than the atmospheric pressure by `rhogh`

C

equal to the atmospheric pressure

D

increases exponentially with depth

Text Solution

Verified by Experts

The correct Answer is:
A

The pressure at depth h below the surface of a liquid of density `rho` open to the atmosphere is `P=P_(a)+rhogh`
where `P_(a)` is the atmosphere 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 `rhogh`.
