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. OWe cannot compare the electric field strengths at points E and C because they are not drawn on the same electric field line. OThe 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

A neutral metal block is located near two balls which have equal positive charges, as shown in the diagram. Use the directional rosette to answer parts b, c, and d. в х ХА 9 zero magnitude metal block (a) Draw the approximate charge distribution on the metal block due to the two positive charges. (b) What is the direction of the net electric field at location B? Enter your number here: (c) What is the direction of the net electric field at location A? Enter your number here: (d) What is the direction of the electric field at location A solely due to the polarized charges on the block? Enter your number here:

Please round off with four decimal points.
