a 1.0kg beaker containgin 2.00kg of oil with a density of 916kg/m3 rests on a scale. a 2.0kg block of iron is suspended from a spring scale and completly submerged in the oil, find the euilibrium readings of both scales.density of iron 7860.

    first the bouyancy supplied to the iron block:

    bouyancy=volume*densityoil=2/7860 * 916

    work that out.

    then the scale above is supporting 2kg-bouyancy.

    the scale below is supporting the beaker, the oil, and the bouyancy force.
