A diver holds two identical square plates, each of area 0.04m2, completely immersed in water at a depth of 5m from the free surface. One plate is kept horizontal while the other is kept vertical. Neglecting any change in depth over the plates, which statement about the magnitudes of the forces exerted by water on the two plates is correct?
(a) The force on the horizontal plate is greater than that on the vertical plate.
(b) The horizontal plate experiences a net downward force of ρghA, whereas the vertical plate experiences no net force.
(c) Both plates experience zero net force, so the forces are equal in magnitude.
(d) The vertical plate experiences a net force of ρghA, while the horizontal plate experiences no net force.
