Question
Two identical floating wooden cubes are attached by pieces of cotton connected to a spring balance. Each object floats in a different fluid, A is in water and B is in oil. The different fluid densities affect how much each objects sticks out above the fluid surface.
Reading the spring balance scales you measure the objects apparent weight, which is the objects real weight minus the buoyant force.
.........................................................
The apparent weight of object A is greater than the apparent weight of object B
The apparent weight of object A is equal to the apparent weight of object B

From these measurements you find ..............................................................
Explanation / Answer
apparant weight = w-B
w' = mobject*g-mfluid*g
w' = qV(rho object-rho fluid)
density of oil is less than the water
so apparant weight of B is more than the object A
