Day 99: Determining the Amount of Charge on Sticky Tape
AP Physics C: If you stick a piece of invisible tape down on table and pull it up quickly, it becomes charged. How much charge is on the tape? What percentage of the atoms on the surface of the tape give up (or gain) an electron? That’s what we were figuring out today. There are several methods. Pictured above is what I call the “angle method.” The group below is levitating the top tape via repulsion from the tape underneath.
While the following group is levitating the bottom tape via attraction.
