Question

A rectangular block of wood floats in water with two-third of its volume immersed .when placed in another liquid,it floats with half of its volume immersed.calculate the relative density of the liquid

Answer 1

Answer:

Let Pw be the density of water and Pl the density of the liquid

W = M g    the weight of the block

W = Pw * 2 V / 3 * g      weight of water displaced

W = Pl * V /2 * g        weight of liquid displaced

Pl / Pw = (2 / 3) / (1 / 2) = 4 / 3
