Question

What is the difference between the pressure on the bottom of a pool and the pressure on the water surface?

• A. $gh$
• B. $\frac{g}{h}$
• C. $0$
• D. $none$

Answer 1

The correct option is A $gh$

The pressure difference is equal to the product of density , height and $g$

Given that $h$ is height difference between bottom and surface of a pool

$P_b-P_s=dgh$

Density $d$ of water is $1$

So we get $P_b-P_s=gh$

Therefore option $A$ is correct
