题目现有质量相等的甲、乙两个均匀实心小球,已知其密度之比ρ甲∶ρ乙=2∶3,把它们放入足够深的水中,当两球静止时所受浮力之比F甲浮∶F乙浮=6∶5,求其密度.此题考查密度、浮力、力的平衡、物体浮沉条件等知识,是一道综合的力学创新题;它着重考查学生分析、解决问题的能力.从? The problem is that the existing equal masses A and B are two uniform solid spheres. It is known that the density ratio ρ A : ρ B = 2 : 3, put them into deep enough water, and when the two balls are still, the buoyancy is affected. Than F Float: F B float = 6:5, seeking its density. This question examines the density, buoyancy, force balance, object floating conditions and other knowledge, is a comprehensive mechanical innovation; it focuses on student analysis, solve problems The ability.
