Physics: What is the pressure on a horizontal surface with an area of 8 msquared that is 4 m underwater? use 1000 kg divided by m cubed for the density of water and 9.8 m divided by s squared for the acceleration due to gravity. what is the correct relationship to use to find the pressure on the horizontal surface?

Explanation:

= depth of water = 4 m

= Area of surface = 8 m²

$\rho$ = Density of water = 1000 kg m⁻³

tex]g[/tex] = acceleration due to gravity = 9.8 ms⁻²

$P_{o}$ = Atmospheric pressure = 101325 Pa

= Pressure at the given depth "h"

Pressure at the given depth is given as

$P = P_{o} + \rho g h\\P = 101325 + (1000) (9.8) (4)\\P = 140525 pa$
