You hook a solid metal block of iron (iron density = 7800 kg/m3) which has a volume of V iron=6.4 X 10^-5 m^3 onto a string and dip it into a beaker of water (water density = 1000 kg/m3. The iron is partially submerged in the water and when the iron block is floating at rest, you find that the tension of the string is 4.5 N. Draw a properly labeled force diagram of the iron block. Find the fraction of the iron that is submerged in the water.
