Question

Two objects labeled K and L have equal mass but densities 0.95Do and Do, respectively. Each of these objects floats after being thrown into a deep swimming pool. Which is true about the buoyant forces acting on these objects?

a. The buoyant force is greater on Object K since it has lower density and lower density objects always float "higher" in the fluid.
b. The buoyant force is greater on Object L since it is denser than K and therefore "heavier."
c. The buoyant forces are equal on the objects since they have equal mass.
d. Without knowing the specific gravity of the objects, nothing can be determined.

Answer 1

Answer:

C. The buoyant forces are equal on the objects since they have equal mass.

Explanation:

Correct option (C) The buoyant forces are equal on the objects since they have equal mass. For floating objects, the buoyant force equals the weight of the objects. Since each object has the same weight, they must have the same buoyant force to counteract that weight and make them float.
