1. The problem statement, all variables and given/known data Archimedes, prove your stuff. A royal crown (cola?) of pure gold is suspended in air by a thread and the tension in the thread is of magnitude T. When the crown is totally immersed in water, the magnitude of the tension in the thread is 0.872T. A) sketch a second law force diagram indicating the forces acting on the crown when suspended in the air. B) sketch a second law force diagram indicating the forces acting on the crown when suspended in water. C) Is the crown made of pure gold or of another metal with just gold plating? (the density of pure gold is 19.3x10^3 kg/m^3) Justify your answer. 2. Relevant equations Fbuoy+Ftension-w=0 3. The attempt at a solution I tried using newtons second law which eneded up getting me that ROHobject(Vobject)+mg+ma=m and If you cancel the m's out you get Rohobject(Vobject)+g=0. Im confused on how to tell how this relates to whether the crown is made of pure gold or another metal.
