Question

While floating in water 5/6 part of volume of a wooden piece is immersed in water. What is the relative density of wooden piece.

Answer 1

Form the floatation law,Weight of the wooden piece = Weight of water displaced by immersed portion orMass of the wooden piece = Mass of water displaced by immersed portion Rdwood × V = Rdwater × VRdwood = Rdwater × 5/6vRdwood  = 1 × 5/6Rdwood = 5/6so, the relative density of wooden piece is 5/6.
