Question

A scuba diver is at a depth of 50 m, while a swimmer is floating at the surface. The liquid pressure experienced by the scuba diver is ________________ than that on the swimmer.

Take, ${\rho }_{water}$ = $1000kg/m^3$ and g = $10m/s^2$

• A. 5000 Pa more
• B. 5000 Pa less
• C. 5000 kPa less
• D. 500 kPa more

Answer 1

The correct option is D

500 kPa more

Given:
ρ = $1000kg/m^3$
g = $10m/s^2$
h = 50 m

Let $P_1$ and $P_2$ be the pressure at the surface and at the scuba driver respectively.
We know that:
$P_2-P_1$ = ρgh
ΔP = 1000*10*50
ΔP = 500 kPa
