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 • A one is true? OThis electric field may be due to a negatively charged object E located to the left. The electric field strengths at points A and D are both zero because there are no electric field lines on them. OThe electric field strength at point C is larger than at point B. The electric field strength at point B is larger than at point C. The electric field strengths at points B and C are the same because they are on the same field line.
