1. A charged rod is placed in a pile of paper confetti. First, the confetti is attracted to the rod,
then it starts jumping off the rod. Explain what is happening in terms of electron flow.
Answers
Flow of Electron
Explanation:
A charged rod is brought near a bit of paper. When the charged rod is brought near the neutral paper, it induces a charge on the side of the paper nearer to the rod. Since unlike charges attract one another, the paper are going to be interested in the rod.
Paper may be a dielectric, so when a charged glass rod is brought near it, atoms of paper get polarized, with center of charge of atoms coming closer to the glass rod. This leads to attraction of the piece of paper towards the glass rod.
When the charged ruler is brought almost the paper pieces, they're interested in the ruler because the the electrons move around on the paper due to the massive charge on the ruler. Electrons will move faraway from the ruler leaving a charge on the paper near the ruler, in order that they are attracted.
