Answer:
the forces are proportional to their areas of application
Explanation:
In a hydraulic jack, Pascal's principle is used, that the pressure in an incompressible liquid is the same at the same height, whereby the pressure on both sides of the jack are the same
P₁ = P₂
the pressure is defined by
P = F / A
we substitute
F₂ =
therefore the force is F₂> F₁
Therefore the forces are proportional to their areas of application
