Question

In FIGURE Q14.5, is p_A larger than, smaller than, or equal to p_B? Explain

Short answer

Pressure on both points are equal. so p_A = p_B

Step-by-step solution

Given information

Two points A and B is shown in the diagram below.

Explanation

The pressure of liquid depends on the density and depth below the surface and atmospheric pressure.

P = hρg + Atmospheric pressure.

Where

P = pressure

h = depth of point from the surface or opening

ρ = density of liquid

g = gravitational acceleration

In this case both will have same height so pressure will remain same.

The floating ship will not impact the pressure on the point below. The weight of ship will be countered by buoyant force.

So p_A = p_B.
