Answer:
The answer is: Pressure increases linearly with the depth
Explanation:
In this case, the definition of pressure is:
where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider , then
.
Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.
So
,
which means that pressure increases linearly with the depth in a factor of .
