In three separate experiments, an object is moved from point \(A\) to point \(B\) in the uniform electric field of a large charged plate (Figure P25.12). The object is at rest in both the initial and final positions. Object 1 carries charge \(+q\) and has mass \(m\); object 2 carries charge \(+q\) and has mass \(2 m\); object 3 carries charge \(-q\) and has mass \(m\). Rank the objects in order of the changes their displacements produce in the electric potential energy of the object-plus-plate system, greatest change first.
