7. Coulomb's equation is used for determining the force between 2 charged bodies separated by a distance F = k 9192 72 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. Show your work and include an image of experiments. Verify your value with research and include citations. b. Using your value of k, determine the electrostatic force for these 2 situations: i. -4C charge is 3cm from a 5C 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-m. Determine the electrostatic force between them. c. Open the full Coulomb's Law simulation to check your work. Describe how you used the simulation and include images for support. 8. Explain how electric forces are like gravitation forces and how they differ.|
