A beaker of mass 1.2 kg containing 2.1 kg
of water rests on a scale. A 2.2 kg block of aluminum (of density 2700 kg/m3) suspended from a spring scale is submerged in the water.
Find the reading of the upper scale (the spring scale). The acceleration of gravity is 9.81 m/s2 . Answer in units of N.
Find the reading of the bottom scale(scale placed under the beaker).
Answer in units of N.
The lower scale supports the beaker, water, and the buoyant force of water on the aluminum
and what about the spring scale?
is it apparent weight = actual weight - densitywater*g*V ?
