If some object is weighed when submerged in water, what will happen to its weight compared to its weight in air?

Increase

Decrease

Remain exactly the same

Increase or decrease cannot be predicted

Explanation:

According to the Archimedes principle, if an object is immersed in a fluid, it experiences an apparent loss of weight which is equal to the weight of fluid displaced.

The buoyant force which acts in the upward direction opposite to the weight of the object causes the apparent loss in weight. In air, the buoyant force is negligible. Hence, the object seems heavier as compared to when it is submerged.
