An object floats with half its volume beneath the surface of the water.The weight (force that Earth exerts in it)of the displaced water is 2000 N.What is the weight (force that Earth exerts on it)of the object? The density of water is 1000 kg/m³. A)1000 N B)2000 N C)4000 N D)It cannot be determined because we do not know the volume of the object.

According to Archimedes Principle, the buoyant force acting on an object submerged in a fluid is equal to the weight of the displaced fluid. Since half the volume of the object is submerged in water, the weight of the displaced water is equal to the weight of the object. Therefore, the weight of the object is also 2000 N.
