Abuoyant force acts in the opposite direction of gravity. according to archimedes’ principle, which of the following is true of an object completely submerged in water?
a. the magnitude of the upward buoyant force on the object is smaller than the weight of the fluid displaced by the object.
b. the magnitude of the upward buoyant force on the object is greater than the weight of the fluid displaced by the object.
c. the magnitude of the upward buoyant force on the object is equal to the weight of the fluid displaced by the object.
