Connected by a string to a scale is an object and when suspended in air, the scale reads 200 N. The scale reads 150 N when the object is suspended in water (d = 1000 kg/m^3). What does the scale read (in N) when the object is suspended in oil having a density of 800 kg/m^3? I determined that the volume of the object was .015 m^3 from using the d=m/v formula in the H2O portion of the problem. I just substituted the volume into the oil density and determined that the mass was 12.24 kg. and then converted that to 120 N. Did I do this correctly?
