Electrostatics Objectives: 1. To use simulations to explore electrostatic interactions. 2. To investigate Electrostatic Force and Electric Fields. Part I: Balloons and Static Electricity Simulation In winter you probably have experienced electrical shock when you take off your sweater. In this part of the lab, you will simulate this phenomenon and examine several basic properties of electric charges. Procedure: 1. Open the following web page: , and click on button. 2. Once your application has started, click “Reset All”. Make sure that only the “ show all charges ” and “ wall ” buttons are selected. 3. Look at the balloon.

The balloon collects all the negatively charged particles and sticks to the sweater that kept all the positively charged particles. 5. How did the balloon get charged, with what type of charge? The balloon got charged from rubbing the sweater and coming into contact with the negatively charged particles in the sweater.

    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.
