The buoyant force is cause by the pressure of displaced fluid pushing up on the object that is displacing the fluid. It acts in opposition to gravity. What is the net force of a piece of Styrofoam submerged in the water that is being pulled down by 20 N of gravity and pushed up by 100 N of the buoyant force?
A. 80 N upward
B. 120 N upward
C. 80 N downward
D. 120 N downward
