A body floats in water with 40% of its volume out side the water. When the body floats in oil, 60% of its volume remainsoutside oil. What is the relative density of oil? |

Answer» Let : V = volume of bodyρ = DENSITY of liquidρ₀ = density of water.= > Weight of body = Upthurst . Weight of body = ( 100 - 40 ) V ρ₀ G / 100= > ( 100 - 60 ) V ρ g / 100Now RELATIVE density : R.D. = ρ / ρ₀= > R.D. = 0.6 / 0.4= > R.D. = 1.5Therefore , relative density of water is 1.5 . |
