Two cubes of side 1.0 msides, one of relative density 0.60 and another of relative density `=1.15` are connected by weightless wire and placed in a large tank of water. Under equilibrium the lighter cube will project above the water surface to a height of

60cc of a liquid of relative densilty 1.4 are mixed with 40 cc of another liquid of relative density 0.8. The density of the mixture is

A U-tube contains water in its lower part. Then 32 cm of kerosene of relative density 0.8 is poured into one limb and a vegetable oil of reative density 0.65 is poured into the other. The water level in the kerosene oil side is 5 cm lower that in the other . what is the height of the column of vegtable oil ?\

A solid body weighs 2.10 N in air. Its relative density is 8.4. How much will the body weigh if placed (i) in water (ii) in a liquid of relative density 1.2 ?
