Step-by-step explanation:
When a surface is submerged in a fluid, the resultant pressure force on the body acts perpendicular to the surface in all directions. This is known as hydrostatic pressure. The pressure at a particular point in a fluid is the same in all directions and is directly proportional to the fluid's density and the depth of the point below the surface of the fluid. As the depth increases, the pressure also increases. The pressure at any point in a fluid is exerted in all directions, so it is a scalar quantity.
This pressure is defined as the force exerted per unit area, and it is determined by the weight of the fluid above the point of interest. The pressure at a point in the fluid is the same in all directions, so it is called an isotropic property of fluid
