Question

An object of mass m , weighs m 1 in a liquid of density d 1 and it weighs m 2 in a liquid of density d 2 . The density d of the object is, d = m 2 d 2 - m 1 d 1 m 2 - m 1, d = m 1 d 1 - m 2 d 2 m 2 - m 1, d = m 2 d 1 - m 1 d 2 m 1 - m 2, d = m 1 d 2 - m 2 d 1 m 1 - m 2

V d - d 1 g = m 1 g V d - d 2 g = m 2 g d - d 1 d - d 2 = m 1 m 2 ∴ d = m 1 d 2 - m 2 d 1 m 1 - m 2
