Relative density of a floating body; experiment to determine the relative density of a cork
Relative density of a floating body:Experiment: To determine the relative density of a corkProcedure:1. Select a sinker which is heavy enough to make the cork to sink.2. Attach the cork and the sinker as follows3. Record the results obtained as followsWeight of the sinker in water= W1Weight of the sinker in water and cork in air = W2Weight of the sinker and cork in water = W3Weight of the cork in air = W2 – W1Upthrust on the cork = W2 –W3The relative density of the cork in air is determined asfollows;d = weight of the cork in air /upthrust on the cork.
