A E The picture shows the field lines of a nonuniform electric field and five points A to E in the field. Consider the following statements. Which one is true? This electric field may be due to a negatively charged object located to the left. A positive point charge placed at point C will feel a stronger electric force than at point D. OThe electric field strengths at points B and C are the same because they are on the same field line. OThe electric field strengths at points A and D are both zero because there are no electric field lines on them. A negative point charge placed at point C will feel an electric force pointing to the right.
