At what situation an object that is submerged in to liquid will rise up

Answer 1

An object that is submerged in liquid will rise up when the buoyant force acting on the object is greater than the gravitational force pulling it down. This buoyant force is generated by the displacement of liquid by the object that is submerged. The buoyant force is equal to the weight of the fluid displaced by the object. As the object displaces more fluid, the buoyant force increases until it exceeds the object's weight, causing it to rise to the surface.
