Chapter 18, Problem 33P

* Figure P18.33 shows $\stackrel{\to }{E}$ field lines in a region of space Note that the distances between A and B, between C and D, and between F and G are all equal. (a) Rank the magnitudes of the $\stackrel{\to }{E}$ field at points A to G from largest to smallest. (b) Rank the electric potentials at points A to G from largest to smallest. (c) A small negatively charged object is moved (I) from A to B, (II) from C to D, (III) from A to D, and (IV) from F to G Rank the work done on the object in these four cases from largest to smallest.
