The buoyancy force is defined as the difference in pressures on the top and bottom of an object submerged in a fluid. When an object is pushing on the top surface of a fluid from underneath, the force of surface tension begins to act downward on the object, preventing it from breaking the surface.
When this is the case (an object being affected by surface tension), do I account for both the forces of buoyancy and the surface tension in my free-body diagram of the object, since there is a very thin amount of fluid on the top of the object?
