When an object is submerged in water, it experiences an upward force exerted by the water, known as the buoyant force. This buoyant force opposes the object’s weight. The apparent weight of the object when submerged is equal to its true weight (weight in air) minus the buoyant force. Since the buoyant force is a positive value for any object submerged in a fluid, the apparent weight will always be less than the weight in air. Therefore, the weight of the object appears to decrease when submerged in water.

– Buoyant force is an upward force exerted by a fluid on a submerged object.
– Apparent weight = True weight – Buoyant force.
– Buoyancy causes the apparent weight to be less than the weight in air.

Archimedes’ principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. The magnitude of the decrease in apparent weight is exactly equal to this buoyant force.
