3. In the diagram below, objects A and B both have a charge of -4.0 nano-coulombs. A B - R - a. Add a set of arrows to the diagram to show the direction in which the electrostatic force acts between objects A and B. b. Using a scale of 1.0 centimeter = 1.5 milli-meters, determine the distance "R" between the charges in meters. C. m Prove that the order of magnitude for the electrostatic force between the two charges is -3.
