Static Electricity Now, hold a neutral insulator ( e.g. the end of a plastic pen or the glass rod, provided that it has been discharged) near each tape and observe what happens . Make sure that you do not allow the insulator to touch the tape. Q10. Describe the interaction between the insulator and each strip. Insulator/T-strip interaction: (a) no interaction (b) they attract (c) they repel Insulator/B-strip interaction: (a) no interaction (b) they attract (c) they repel Q11. Using a few sentences and a clear sketch, explain these observations. Your sketch should show how the different charges in the insulator (again, you can just indicate charges with “plusses” and “minuses” ) are distributed when the insulator is far away from a charged tape strip and when it is close to a charged tape strip. Sketch: Q12. Based on your observations, which was stronger: the interaction between the conductor and the tape strips or the interaction between the insulator and the tape strips? Explain this observation.
Static Electricity Analysis Q13. If you observe that two objects are electrostatically attracted to each other, are they necessarily oppositely charged? Q14. Offer an explanation as to why the charged strips of tape are attracted to your finger when you bring it close to the strips.

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
