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 • A true? OThe electric field strength at point C is larger than at point B. OA negative point charge placed at point C will feel an electric force pointing to the right. We cannot compare the electric field strengths at points E and C because they are not drawn on the same electric field line. The electric field strengths at points A and D are both zero because there are no electric field lines on them. This electric field may be due to a positively charged object located to the right. E
