题现有一个匀质杠杆(其重力不计)AB,两端各悬挂一物体(密度均大于液体的密度),此时杠杆平衡,如果将两个物体同时都浸没在液体中如图所示,则此时杠杆是否还能保持平衡?解设A端所挂物体的重力为G,密度为ρ1,体积为V1;B端所挂物体的重力为G2、密度 The problem is that there is a homogenous lever (whose gravity is not counted) AB, and an object is suspended at both ends (the density is greater than the density of the liquid). At this time, the lever is balanced if the two objects are immersed in the liquid at the same time as shown in the figure. In this case, whether the lever can maintain balance? Solve the gravity of the object hung on the A side is G, the density is ρ1, the volume is V1; the gravity of the object hung on the B side is G2, density
