Chapter 20, Problem 46PCE

Figure 20-35 shows a series of equipotentials in a particular region of space, and five different paths along which an electron is moved. (a) Does the electric field in this region point to the right, to the left, up, or down? Explain. (b) For each path, indicate whether the work done on the electron by the electric field is positive, negative, or zero. (c) Rank the paths in order of increasing amount of work done on the electron by the electric field. Indicate ties where appropriate. (d) Is the electric field near path A greater than, less than, or equal to the electric field near path E? Explain.
