Is more work, less work, or the same amount of work needed to move a positive test charge from infinity to an equipotential contour that is 0.1 m from the charge in figure 2 compared to the work needed to move the test charge to a position 0.2 m away?

How much work is needed to move a charge from one position to another that is on the same equipotential contour?

Sketch electric field lines and at least three equipotential contours for an isolated negative charge.

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. Did any of your equipotential surfaces cross? Should they?...

Suppose that a positive test charge q0 moves through a displacement d s→from one equipotential surface to the adjacent surface. The work the electric field does on the test charge during the move is –q0dV. The work done by the electric field may also be written as the scalar product (q0E→)·d s→, or q0E(cos θ) ds. It's a general question what if the test charge is negative? what happens to the displacement and work?

12. a. You do 31 J of work to move a -15 uC from infinity to a spot some distance away from a -11 uC charge. What is that distance? [4.8 cm] b. The work you did is stored as potential energy in the system as long as the charges are both held fixed in that position. You then let the -15 uC charge go. If that point charge has a mass of 7.2x10-12 kg, how fast will it be...
