    Buoyancy of a pail of water problem

    So buoyant force will be added? I got it. How about if water spills? The spilled water will be the buoyant force that will be out of the pail. However, the object exerts a force equal but opposite of the buoyant force, so it adds weight? correct?

    Buoyancy of a pail of water problem

    So it adds weight. The weight added will be the weight of the object when in air, since buoyant force will be cancelled?

    Buoyancy of a pail of water problem

    before, the tension is the weight of the object. when submerged, the tension change since there is a bouyant force that acts on the object. Am I correct?

    Buoyancy of a pail of water problem

    Well, I think it does not add. Since the object is hung? Am I correct?

    Buoyancy of a pail of water problem

    I have a question, if a hung object is submerged in a pail of water, does the weight of the pail with water increase. The object is still hung and no water spills.

    Forces help

    Draw free-body diagrams of each object and the forces acting on them. If two objects are connected by a single string, then they have the same tension.

    Mass density of a sphere

    let say: D = Density m = mass v = volume D1 = 1.4 kg/m3 mass is constant since the air will only be compressed. D = m/v yielding m = Dv Therefore, D1v1=D2v2 but v of sphere is (3*pi*r3)/4 and r2=r1/2 You can get it now.
