A negative charge is placed between a pair of oppositely charged plates, as shown. (IMAGE)
Which best describes the result of moving the charge to the point marked X?
Its electric potential energy increases because the electric potential increases.
Its electric potential energy increases because the electric field increases.
Its electric potential energy stays the same because it has the same electric field.
Its electric potential energy stays the same because it has the same electric potential.
Its electrical potential energy stays the same because it has the same electric potential. The reason why is that moving the charge towards X does not change the distance of the negative charge between the plates. The Electrical potential energy of a particle is the result energy by virtue of its position from the electrical fields produce by the plates both positive and negative. Since the charge is still equidistant to each other (assuming based from the diagram) no change in terms of electrical energy consumption or work was done.
