Question

A ball is made of a material of density ρ where roil < ρ < ρ_water with ρ_oil and ρ_water representing the densities of oil and water, respectively. The oil and water are immiscible. If the above ball is in equilibrium in a mixture of this oil and water, which of the following pictures represents its equilibrium position?

Answer 1

(c) : As ρ_oil <ρ_water, so oil should be over the water.
As ρ > ρ_oil, so the ball will sink in the oil but ρ <ρ_water so it will float in the water.
Hence option (c) is correct.
