A fixed particle with an unknown charge uniformly distributed about its volume is shown. The vectors shown point in the direction of the electric field and the color of the vectors represent the field's magnitude. Distance is measured in m.
Determine the charge on the particle in Coulombs and the number of excess electrons that are on the sphere by dragging the test charge. Start
0.39 nC or 2.4x109 electrons.
