7. The electric field lines in a region of space are shown in the diagram below. The dashed line indicates the path of a positively charged particle that is free to move in this field, subject only to the electric field represented by the field lines. a. Consider the path of the charged particle and decide if the field along each line should be roughly left to right or right to left. Explain how you arrived at your answer. b. Place three points in a drawing representing points A, B, and C, and draw arrows at each point representing the electric field there. Make the arrow point in the direction of the field and make its magnitude roughly represent the magnitude of the field (i.e.. small, intermediate, and large).
