Answer:
100 N
Step-by-step explanation:
The weight of the displaced water is equal to the weight of the body in air minus its weight in water. This is because when an object is submerged in water, it displaces a volume of water equal to its own volume, and the weight of the displaced water is equal to the buoyant force acting on the object.
So, in this case, the weight of the displaced water is:
500 N - 400 N = 100 N
Therefore, the weight of the displaced water is 100 N.
