Document Summary
Chapter 18: electric forces and fields: explain how a neutral conductor is attracted to a charged object. Exam 1 physics b study guide: conductors are substances that conduct electric charge generally well. Metals like silver or gold are good conductors and are used in electric wiring. It will be attracted to the charged object. This happens because electrons the uncharged object will migrate toward a positive charge and away from a negative charge. Since the attractive force on the near side is stronger than the repulsive force on the far side, there will be a net attractive force: explain how a neutral insulator is attracted to a charged object. Insulators are substances that conduct electric charge poorly. When the rod is removed, this allows for the electrons to distribute themselves all over the surface of the sphere. If the rod is negatively charged, then it will spread a negative charge over the surface.
