Question

At the same depth, atmospheric pressure is .............. water pressure.

• A. greater than
• B. lesser than
• C. equal to
• D. none of these

Answer 1

The correct option is B lesser than

As pressure at depth ${}^{\prime }{h}^{\prime }$ is given by
$P=P_o+\rho gh$
Also density of water is more than density of air i.e. ${\rho }_{water}>{\rho }_{air}$
So, at the same depth, water will exert more pressure than air atmosphere.
