Final answer:
The closer together the charges are the stronger the electric field between them. When drawing an electric field between two charges, spacing the field lines farther apart would indicate that the field strength is weaker.
Step-by-step explanation:
The closer together the charges are the stronger the electric field between them. When drawing an electric field between two charges, spacing the field lines farther apart would indicate that the field strength is weaker. For example, in the case of like charges, the field lines are farther apart because the fields from each charge exert opposing forces on any charge placed between them. On the other hand, in the case of unlike charges, the field lines are closer together because the fields from each charge are in the same direction and add up in strength. The strength of the electric field is proportional to the number of field lines per unit area perpendicular to the lines.
