Exercise 7 Two large horizontal metal plates are arranged one above the other a short distance apart in a vacuum. A small, negatively charged sphere introduced between them may be held stationary if an appropriate potential difference is applied to the plates. Explain how (if at all) the equilibrium of the spheres might be affected if the plates were slowly pulled apart while remaining connected to the source of EMF.
