Use your understanding: 7. Coulomb's equation is used for determining the force between 2 charged bodies separated by a distance. F = k4132 r The variables are k (Coulomb's constant), q (charge of body in Coulombs, C), r (distance between bodies in meters), and F (electrostac force in Newton, N) a. Use measurements to determine Coulomb's constant for at least 3 situations. Show your work and include an image of experiments. Verify your value with the textbook. Charge, q1 Charge, qz Distance, r Force, F Coulomb's constant (k) b. Using your value of k, determine the electrostatic force for these 2 situations: i. -4p.C charge is 3cm from a SuC 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 5.3x10'11m. Determine the electrostatic force between them. c. Check your work by using the simulation. 8. Explain how electric forces are like gravitation forces and how they differ
