07.35: Two objects lbnh9w4 z:lbt1e y3i e4 cw6sja ( 8dp0fg6nnha 6/aow(abeled K and L have equal mass but densities 0.95D0 and D0, respectively. Each of these objects floats after being thrown into a de0 wnjc6aw anad ph8s ((6/g6ofep 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.
