A negatively charged graphite-coated sphere is suspended from the ceiling on an insulating string in the region between oppositely charged parallel plates, as illustrated below. The plates are 20.0 cm apart and are maintained at an electrical potential difference of 3.1 x 102 V. The charged sphere experiences an electrical force of 8.4 x 107 N.
