Will the weight of an ‘iron sinker plus cork’ combination in water be more or less than that of the iron sinker alone in water? Give a very brief explanation for your answer.

Ans. The weight of the iron sinker plus cork combination, underwater, will be less than the weight of the iron sinker alone underwater. The buoyant force, on the cork, when fully immersed in water is more than the weight of the cork itself. This implies that the effective weight of the cork in water is actually negative. As a result the combined weight of the iron sinker and the cork is less than the weight of the iron sinker alone.
