Apparent weight of immersed bodies

AI Thread Summary
To determine the relative density of the object, first apply Archimedes' principle, which states that the buoyant force equals the weight of the water displaced. The weight of the object in air is 250N, while its weight when immersed in water is 150N, indicating a buoyant force of 100N. This buoyant force corresponds to the weight of the water displaced, which can be used to find the volume of the object. The relative density can then be calculated by dividing the weight of the object by the weight of the displaced water. This approach provides a clear method for solving the problem using fundamental principles of physics.
