Blocks a, b, and c in FIGURE Q14.7 have the same volume. Rank in order, from largest to smallest, the sizes of the buoyant forces F_{a} , F_{b} , and F_{c} on a, b, and c. Explain.

Buoyant forces are equal on all three blocks, so F_{a} = F_{b} = F_{c}

The figure given with 3 objects with same volume is submerged in liquid.

We know that buoyant force acting on a mass floating in a liquid depends on density of object, submerged volume of object and gravity.

F= V_{s} ρ g ……..................(1)

Where

F = buoyant force

V_{s} = submerged volume

ρ = density of liquid

g = gravity

As the volume of all objects are same so buoyant force will be same .

So.

Fa = Fb =Fc
