Answer
The iron would not balance the feathers.
On a sensitive equal-arm balance, the iron will sink compared to the feathers.
Work Step by Step
According to Archimedes’s Principle, the buoyant force equals the weight of the displaced fluid.
Iron is denser than feathers, meaning it takes up less volume for its weight. When submerged in air, a pound of iron will feel a smaller buoyant force than a pound of feathers, because the iron displaces less air.
On a sensitive equal-arm balance, the iron will sink compared to the feathers.
