A sphere of mass of m = 1.30 kg is first placed directly on the plate of an electronic scale. The scale shows 12.75 N as the weight of the object. A large beaker containing a liquid with a density of ?liquid = 853 kg/m3 is 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. ( The scale reads 1.70 N with the sphere not touching the beaker. Calculate the density of the sphere.
