Pressure on a horizontal planar surface under water acts ____.
A)parallel to the plane
B)shear to the plane
C)at various angles to the plane
D)perpendicular to the plane

Question

Quizplus · Accepted Answer

Pressure under water acts perpendicular to the planar surface. This is because the pressure at any point in a fluid is transmitted equally in all directions, and in the case of a horizontal surface, the force due to the pressure is only acting in the vertical direction, thus resulting in a perpendicular force.
