Download Electrostatics - General Physics II - Laboratory | PH 102 and more Lab Reports Physics in PDF only on Docsity! University of Alabama Department of Physics and Astronomy PH 102-2 / LeClair Spring 2008 In-class Exercise: Electrostatics In today’s class we will investigate charge distributions and electric forces using online simulation “applets." You can find the applet here. Alternatively, you can go to the course web site and follow the link there. The password & username to access these applets will be given in class. Exercise I 1. Open up “Exploration 22.2: Explore the Effect of Multiple Charges."i 2. Follow the procedures and answer the questions at the bottom of the page. Type your responses into, e.g., Word or Notepad as you are doing this. You will need to include screenshots in your lab report at later stages. Be sure to include all group member’s names at the top of this document. 3. When you have finished question g, take a screen shot of your configuration (hint: four charges works well). Instructions on how to do this are below. Put this screenshot into your lab report document. If you use Microsoft Word, this is easily accomplished – ask if you are unsure. 4. Finish all the questions for this exercise. Your lab report document should contain all of your answers, clearly marked by exercise and question number, all group member’s names, and your screenshot. 5. Keep your document open for the second exercise ... Exercise II After you have finished the first exercise: 1. Go back to the table of contents (the link above). 2. Open up “Exploration 22.6: Run Coulomb’s Gauntlet." 3. Follow the procedures and answer the two questions at the bottom of the page. Finding a working config- uration of charges is difficult, but it can be done with 3 additional charges if you think carefully before you start. 4. Record these responses in the same document as Exercise I. 5. When you have finished question g, take a screen shot of your best configuration. You will not be penalized if you could not find a working solution, only if you do not try. iBe sure you choose “Exploration 22.2," not “Illustration” or “Problem” 22.2
