A beaker of mass mb containing oil of mass m1 and density ρ1 rests on a scale. A block of iron of mass m2 and density ρ2 is suspended from a spring scale and completely submerged in the oil. Determine the equilibrium readings of both scales. (Use rho_1 for ρ1, rho_2 for ρ2, m_1 for m1, m_2 for m2, m_b for mb, and g when necessary.)

    The idea here is to calculate the bouyant force in each liquid, and add that to the original mass, since the scale is now supporting that mass.


    the reading on the scale will then be
