A metal ball with a diameter of 7 cm, is insulated and charged with a positive electric charge of +8.5 microcoulombs , which is fixed over an insulator as shown in the figure. A light polystyrene sphere with a diameter of 3 cm, wrapped in a metallic sheath and suspended by an insulating thread, has a negative charge of -9 nanocoulombs in equilibrium near the metal sphere. Calculate the electrical force exchanged between the two spheres.
