Two cylinders of the same mass are suspended from the balance beam: lead and aluminum. The balance is in equilibrium. Will the balance of the balance be imbalanced if both cylinders are simultaneously immersed in water? Alcohol?
The masses of the lead and aluminum cylinder are equal, therefore, the volume of the aluminum cylinder is greater: ma = mс and ρа * Vа = ρс * Vс; ρс / ρа = 11300/2700 = Vа / Vс (Vа> Vc).
When immersed in a liquid, the taken cylinders will additionally be acted upon by the Archimedes force, which depends on the volume of the body. Consequently, a large buoyancy force will act on the aluminum cylinder and the balance of the used weights will be imbalanced.
The imbalance will occur regardless of the type of fluid.
