Coulomb’s equation is used for determining the force between 2 charged bodies separated by a distance   The variables are k (Coulomb’s constant), q (charge of the body in Coulombs, C), r (distance between bodies in meters), and F (electrostatic force in Newton, N) 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. Using your value of k, determine the electrostatic force for these 2 situations: -4µC charge is 3cm from a 5µC charge. 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.
