Three objects (m1, m2, and m3) are submerged completely in three unknown fluids (

). Each object is attached to a scale by a string. All the objects are stationary as shown.

The three objects have the same volume, but unknown masses.

The scales all show the same reading. How must the masses of the three objects compare?

Since all three objects have the same volume and the scales are showing the same reading, we can determine that the masses of the three objects must also be the same.

Therefore, m1 = m2 = m3.
