07.35: Two objects labeled K and L have equal ma 9z:f8(hd(lys6 ,c6uukkr gn qss but densities 0.95D0 and D0, 6h6g(:us cd zl,u8nfqy k(kr9 2+rfi0lb/hnv respectively. Each of these objects floats after being thrown into a deep swimming pool. Which is true about the buoyant f2 n0hfvlib/+rorces 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.
