Law: Archimedes' Principle
"When a body is partly or wholly dipped in a fluid, the fluid exerts a force on the body due to hydrostatic pressure. At any small portion of the surface of the body, the force exerted by the fluid is perpendicular to the surface and is equal to the pressure at that point multiplied by the area. The resultant of all these constant forces is called upthrust or buoyancy."
Maharashtra State Board: Class 11
Definition: Upthrust / Buoyancy
The resultant of all the forces exerted by a fluid on a body partly or wholly dipped in it, due to hydrostatic pressure, is called upthrust or buoyancy.
