Electric fields and charge 4 electrostatic force in atomic physics the electrostatic force binds electrons and nuclei together to form atoms and the same force holds atoms and molecules together in bulk material. The reality of an electric field is a topic for philosophers. Electrostatic phenomena arise from the forces that electric charges exert on each other. You can move charges around and see the force, you can observe the electric field generated by charge configurations and observe the motion of test particles in electric fields. Pdf electric forces and electric fields quick quizzes. If the idea of force acting at a distance in coulombs law seems troublesome, perhaps the idea of force caused by an electric field eases your discomfort somewhat.
