A sphere of mass ofm= 1.40 kg is first placed directly on the plate of an electronic scale. The scale shows 13.73 N as the weight of the object. (See left figure.) A large beaker containing a liquid with a density of ?liquid= 725 kg/m3is then placed on the scale and the scale is tared (i.e. zeroed to this weight as a reference point, it has a reading of zero with the beaker on the scale). The sphere, hung by a thin string, is lowered into the liquid and submerges below the surface. (See right figure.) The scale reads 1.25 N with the sphere not touching the beaker. Calculate the density of the sphere. Can I have the answer and formulas in deatail. Assume that I dont know what any of the variables stand for.
