If he immersed the cork completely in the tap water, then what will be the weight of the cork now?

While performing an experiment, Archimedes’ principle, Raj took a cork of 5 cm3 volume and observed it weight as 20 g-wt using a spring balance. If he immersed the cork completely in the tap water, then what will be the weight of the cork now?

Apparent loss in weight = Weight of water displaced = 5 cm3
∴ Upthrust = 5 g
∴ Apparent weight in water = (20 - 5) = 15 g-wt.
