An object floats with half its volume beneath the surface of the water. The weight of the displaced water is 2000 N. What is the weight of the object? The density of water is $1000 \mathrm {~kg} / \mathrm { m } ^ { 3 }$
A) 2000 N
B) 4000 N
C) 1000 N
D) It cannot be determined because we do not know the volume of the object.

Question

An object floats with half its volume beneath the surface of the water. The weight of the displaced water is  2000 N. What is the weight of the object? The density of water is $1000 \mathrm {~kg} / \mathrm { m } ^ { 3 }$
A)  2000 N
B)  4000 N
C)  1000 N 
D) It cannot be determined because we do not know the volume of the object.

Quizplus · Accepted Answer

The weight of the object is equal to the weight of the displaced water, which is 2000 N, because the object is floating and in equilibrium, meaning the buoyant force (equal to the weight of the displaced water) balances the object's weight.
