Each of these objects ig *udlz cb3 f*q.lg(7f 6b9psfloats after being thrown into a deep swimming pool. Which is true about the buoyant forces acting on these objects?
A. Buoyant force is greater on K since it has a lower density and displaces more water.
B. Buoyant force is greater on K since it has lower density and lower density objects always float “higher” in the fluid.
C. Buoyant force is greater on L since it is denser than K and therefore “heavier.”
D. Buoyant forces are equal on the objects since they have equal mass.
E. Without knowing the specific gravity of the objects, nothing can be determined.
