Question

Quizplus · Accepted Answer

The water level remains the same because the amount of water displaced by the combined volume of wood and iron does not change when their positions are switched. The buoyant force equals the weight of the water displaced, which is determined by the total volume of the wood and iron together, not their arrangement.
