Question

The weight of a floating body in air is 450kgf and the appparent weight in water is 350kgf what is the uptrust exerted by the water

Answer 1

Mass in air = 450g

Mass in water = 350g

Weight loss = 100g

According to Archimedes principle weighted the water displaced = buoyant force = weight loss

Therefore upthrust exerted by the water is 100N
