Question

The pressure $P_1$ at a certain depth in river water and $P_2$ at the same depth in sea water are related as:

• A. >
• B. <
• C.
• D. = Atmospheric pressure

Answer 1

The correct option is B

<

Liquid pressure is given by, P = $\rho$gh. Since the density of sea water is more than that of river water, the pressure at a depth of sea water will be more than that in river water. So, $P_1$ < $P_2$.
