Question

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.

Short answer

Buoyant forces are equal on all three blocks, soF_a = F_b = F_c

Step-by-step solution

Given information

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

Explanation

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
