Which of the following must ALWAYS be equal to the buoyant force on an object?
A.the force of gravity
B.the weight of the object
C.the weight of the liquid displaced by the objec
D.the force of friction as the object moves in the water
C-the weight of the liquid displaced The magnitude of the buoyant force is calculated by measuring the weight of the fluid displaced. Friction acts in a different plane to the buoyant force as it moves through the water therefore it is not d.
