| - | You have become trapped in the town of Lakeview. The town and surrounding landscape are under a constant barrage of storms. Not only are people being struck by lightning within the town but any vehicle or person trying to leave the city limits of Lakeview are instantly struck by lightning. The number of deaths due to lightning strikes in Lakeview in one week is larger than the amount the whole world has seen in the last 5 years. Jo Harding, a crazy local scientist who has had a few run-ins with storms before has an idea of putting up giant metal T's, with the base of the T inserted into the ground to try and stop the townspeople from being struck with lightning. Jo wants the base of the T to be made of wood and the horizontal top of the T to be a metal. Mayor Rachel Wando is up for reelection and is willing to listen to any ideas to stop the rising death toll but ever since the lightning storms started she has been in non-stop meetings in which electric fields are being constantly talked about and is becoming very concerned about what the electric fields would be like for these T-shaped objects. Rachel reaches out to her friends at the storm chaser HQ for a model of what the electric field will be for one of these T's after it has been struck by lightning. The code below is the beginnings of your teams work on modeling the electric field from the giant T. | + | You have become trapped in the town of Lakeview.

| + | Conceptual Questions | ||
| + | - How do you know if your code is working correctly? | ||
| + | - What is superposition and how did you make use of it in the code? | ||
| + | - If you had to calculate the electric field by hand (at a single observation point), what steps would you have to use? | ||
| + | - What is the difference between an insulator and conductor? | ||
| + | - 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? | ||
| + | - If you change the radius for your observation points, what happens to your E-Field arrows? Is that expected? Why or why not? | ||
| + | - What are the limitations of this model? How could you improve your model? | ||
