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 1) . 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 2m; 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.

Rank from greatest to smallest. To rank items as equivalent, overlap them.
