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.Figure1 of 4Part A(Figure 1) shows two different ways to visualize an electric field. On the left, vectors are drawn at various points to show the direction and magnitude of the electric field. On the right,electric field lines depict the same situation. Notice that, as stated above, the electric field lines are drawn such that their tangents point in the same direction as the electric fieldvectors on the left. Because of the nature of electric fields, field lines never cross. Also, the vectors shrink as you move away from the charge, and the electric field lines spread outas you move away from the charge. The spacing between electric field lines indicates the strength of the electric field, just as the length of vectors indicates the strength of theelectric field. The greater the spacing between field lines, the weaker the electric field. Although the advantage of field lines over field vectors may not be apparent in the case of asingle charge, electric field lines present a much less cluttered and more intuitive picture of more complicated charge arrangements.OWhich of the following panels (labelled A, B, C, and D) in (Figure 2) correctly depicts the field lines from an infinite uniformly negatively charged sheet?
