4. 5 Forces on Conductors(see Fig 4-5) Consider a conductor with surface charge density o A small element da on the conductor carries charge oda. It experiences an electric field due to all the other charges on the conductor Near the surface of the conductor the field is e o/E0, it is normal to the surface and points outward The force acting on oda is what? F=E(oda)? No The total field is E=o/ E0, but the portion produced y oda is only(gauss law) 2∈02 Other charges on the conductor produce another de
