在学习中常有两类浮力大小的比较问题.一类是同一物体(密度为ρ物)别放到密度为ρ1、ρ2的两种液体中,当物体静止时它在哪种液体里受到浮力大.另一类是两个物体同放在一个液体中,当它们静止时,哪个物体到的浮力大(设两物体密度分别为ρ1、ρ2,液体密度为ρ液).解决这两类问题的 There are two types of buoyancy comparison problems in the learning process. One is that the same object (density ρ) should not be placed in two liquids with density ρ1 and ρ2. When the object is stationary, which buoyancy force it is exposed to? The other type is that two objects are placed in the same liquid. When they are stationary, which object has a large buoyancy (set the two objects to be ρ1 and ρ2 respectively and the liquid density is ρ liquid). Solving these two types of problems
