1. Refer to the following two images for the questions that follow. a) Refer to Figure 1: i) State whether the source charge is positively or negatively charged. ii) Figure 1 contains arrows that are outwardly pointing. By convention, state how the directions of field lines are detected. b) Comparing Figure 1 and Figure 2, you can see Figure 2 does not have any arrowheads. Observe the sign of charges for each source charge, (in Figure 2) and state the direction the arrowheads should be pointing to make it accurate.
