+ | Things have gotten weird in the town of Lakeview. After sighting the strange cloud earlier in the week, the clouds only become more frequent. The town and surrounding landscape are now under a constant barrage of storms, and there are rumors of strange creatures lurking in the woods near town. Several | ||

- | The code below is the beginnings of your team's work on modeling the electric field from the giant T. Complete the program above to first represent the total electric field just to the right and left of the line of charges. Then, calculate the total electric field at a range of points surrounding the line of charges. | + | The code below is the beginnings of your team's work on modeling the electric field from the giant T.

- We assumed in this problem that the charge was divided equally among the spheres in our model. Is that a good assumption for conductors? Is that a good assumption for insulators? Why or why not? | - We assumed in this problem that the charge was divided equally among the spheres in our model. Is that a good assumption for conductors? Is that a good assumption for insulators?
