You need to determine the density of an object. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the object into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density of the object? Two significant digits. (Hint: Recall tension in a string and the volume of displaced fluid for an object completely submerged) in our examples. Use: Density of water as 1000 kg/m3.
