Item 7Learning Goal:To understand the nature of electric fields and how to draw field lines.Electric field lines are a tool used to visualize electric fields. A field line isdrawn beginning at a positive charge and ending at a negative charge. Fieldlines may also appear from the edge of a picture or disappear at the edge ofthe picture. Such lines are said to begin or end at infinity. The field lines aredirected so that the electric field at any point is tangent to the field line atthat point.FigureBDMNM3 of 4Part CWhich of the following panels (labelled A, B, C, and D) in (Figure 3) shows the correct electric field lines for an electric dipole?OABSubmitPart DIn (Figure 3), what is wrong with panel D?
