Two bodies are in equilibrium when suspended in water from the arms of a balance. The mass of one body is 28 g and its density is 5.6 g/c.c. If the mass of the other body is 36 g, find its density d.

1.	Two bodies are in equilibrium when suspended in water from the arms of a balance. The mass of one body is 28 g and its density is 5.6 g/c.c. If the mass of the other body is 36 g, find its density d.
Answer» Solution :Weight of water displaced by first BODY `=28/5.6g` Weight of water displaced by second `=36/dg`, Apparent weight of first body `(28-28/5.6)G` Apparent weight of second body `=(36-36/d)g` SINCE bodies are in EQUILIBRIUM `(28-28/5.6)g=(36-36/d)g""d=36/13~~2.8` g/cc
