Short Answer

Blocks a, b, and c in FIGURE Q14.7 have the same density. This

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

See the step by step solution

Step by Step Solution

Step 1. Given information

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

Step 2. Explanation

Buoyant force acting on a mass floating in a liquid depends on density or object, submerged volume of object and gravity.

F = Vsρg ....................(1)

Where

F = buoyant force

Vs = submerged volume

ρ = density of liquid

g = gravity

We know that the density of the blocks are same so volume of block will be

V = Mass / Density

Given Ma = Mb = 50 g and Mc=40g

So, the expression is given as

Va = Vc > Vb

From the equation (1) we understand that Buoyant force depends on the Volume submerged if density of liquid is same.

Fa = Fc > Fb.
