Electrons coat each individual hair fiber and then repel each other. 1. Charge and Electric Flux A charge distribution produces an electric field (E), and E exerts a force on a test charge (q ). By moving q around a closed box that contains the charge distribution and measuring F one can make a 3D map of E = F/q outside the box. From that map, we can obtain the value of q inside box. If we construct a boundary around a charge, we can think of the flow coming out from the charge like water through a screen surrounding a sprinkler. Electric Flux and Enclosed Charge:There is a connection between sign of net charge enclosed by a closed surface and the direction of electric flux through surface (inward for q, outward for +q). There is a connection between magnitude of net enclosed charge and strength of net “flow” of E....
