An aluminum object suspended from a string with density 2700 kg/m^3 is submerged into ethyl alcohol.
what is the tension in the string? V=142 cm^3
The Attempt at a Solution
I tried to multiply the volume 142 cm^3 (.000142 m^3) by the density 2700 kg/m^3 to get the mass. Then I multiplied the mass by gravity since Archimedes' principle tells us that Ethyl Alcohol pushes with a force equal to the weight. But that is wrong for some reason. Please help me. Thank you.
