A solid glass object weighs 10.192 N in air. It has a volume of4Ã10-4m3. Later, it is
completely immersed in ethyl alcohol at the end of a spring scale.The density of ethyl
alcohol is 790 kg/m3. The buoyant force due to air is negligible.The buoyant force due to ethyl alcohol is 3.0968 N.
a) What is the reading of the spring scale when the object iscompletely immersed in
ethyl alcohol?
b) Find the density of glass.
I am confused on how to set up this problem. The use of the springscale in the problem really confuses me. Thanks for your help!
