question archive How many equipotential surfaces did we draw in this lab for each mapping? 1)In the first mapping, where is the electric field weaker and why? 2) In the first mapping, where is the electric field stronger and why? 3) In the third photograph, why was the electric field not drawn through the black circle? 4)In the same mapping, why was the equipotential drawn around the black circle? 5)What is the electric potential at the center of the black circle? How does it change as we move from the center to the surface of the black circle? How does it change as we go out of the black circle? 6) What does the white circle represent in Figure 3? What is the electric potential and field in the white circle? Explain your answer

How many equipotential surfaces did we draw in this lab for each mapping?
1)In the first mapping, where is the electric field weaker and why?
2) In the first mapping, where is the electric field stronger and why?
3) In the third photograph, why was the electric field not drawn through the black circle?
4)In the same mapping, why was the equipotential drawn around the black circle?
5)What is the electric potential at the center of the black circle? How does it change as we move from the center to the surface of the black circle? How does it change as we go out of the black circle?
6) What does the white circle represent in Figure 3? What is the electric potential and field in the white circle? Explain your answer.
For the pattern used in Fig. 1 determine the average potential gradient at two points along a straight line connecting the two electrodes in the following manner:
(a) Measure the distance between the 1.0 V and 0 V equipotential lines, ?s.
(b) Determine ΔV/Δs = 1.0V/Δs = (Δs in meters).
What does this value represent? What is it proportional to?
(c) Repeat using the 2.5V and 3.5V equipotential lines.
(d) What do the relative values of the two potential gradients indicate? Is this what you would expect? Why?
(e) If a positive charge moves along the electric field line, what happens to its potential and kinetic energy?
(f) What is the work done in moving a charge along the equipotential surface? Explain your answer.
