What is the displacement of the object?

Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
