Two negatively charged objects A and B are charged and create an electric field. The electric field strength at a point precisely midway between these two charges is 10 N/C, directed leftward. This provides evidence that .

Ne way in which elements differ from each other is the structure of the electron cloud in each element's atoms. in an electron cloud, an electron that is farther away from the nucleus has
