  1. Did any of your field lines cross? Should they? Why, or why not?

None of the field lines crossed, nor should they. They are a line of constant potential and the equipotential can have only one value at a given point in space. If the electric field lines were to intersect, they would render a location with two different strong electric field vectors and so would not accurately represent equipotential lines.

  1. Did any of your equipotential surfaces cross? Should they? Why or why not?

The equipotential surfaces did not cross, nor should they. They represent a position of points that all harness the same, or constant, electrical potential. If the surfaces were to cross, then at the point of intersection, there will be two different values of electric potential, which is not possible.

  1. Sketch the electric field lines and equipotential surface intersections; one expects around two equal positive point charges.
  1. Make a similar sketch for two equal negative point charges.
  1. What do you conclude about the distribution of the electric field lines for circular and line charge distributions?

Escaping field lines Charges 2q and −q are located on the x-axis at x = 0 and x = a, respectively.(a) Find the point on the x-axis where the electric field is zero, and make a rough sketch of some field lines.(b) You should find that some of the field lines that start on the 2q charge end up on the −q charge, while others head off to infinity. Consider the field lines that form the cutoff between these two...
