Question: An 11.2-g piece of Styrofoam carries a net charge of -0.68 µC and is suspended in equilibrium above the center of a large, horizontal sheet of plastic that has a uniform charge density on its surface.
Part A: What is the charge per unit area on the plastic sheet?
Please explain each step and equations used for above question.
