SUMMARY
The force required to submerge a 5 kg object in water, which displaces 10 kg of water, is 49 N. This conclusion is derived from calculating the buoyant force, which equals the weight of the displaced water (10 kg * 9.81 m/s² = 98.1 N). To submerge the object, the applied force must counteract both the buoyant force and the weight of the object itself. Therefore, the net force required is 49 N, accounting for the downward force exerted by the object.
