7. Coulomb's equation is used for determining the force between 2 9192 7-2 F = kª charged bodies separated by a distance The variables are k (Coulomb's constant), q (charge of body in Coulombs, C), r (distance between bodies in meters), and F (electrostatic force in Newton, N) a. Use measurements to determine Coulomb's constant for at least 2 situations. b. Using your value of k, determine the electrostatic force for these 2 situations: i. -4µC charge is 3cm from a 5µC charge. ii. An electron has a charge of -1.6x10-¹9C and a proton has a charge of 1.6x10-¹⁹C. In a hydrogen atom, the distance between them is 5.3x10-¹m. Determine the electrostatic force between them. c. Open the full Coulomb's Law simulation to check your work. Describe how you used the simulation
