PPT-Interaction of Charged Objects

Attraction can happen also for likecharged objects Repulsion can happen only for likecharged objects Intervening matter does not block the E field The resulting field is a . Lesson 1:.

Inducing a Charge on a Conductor (Polarization). Essential Knowledge. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. 9.3, 9.4, 9.8, 9.7. What rooms in your house and school seem to produce the worst shocks from static electricity?. What can you do to minimize or eliminate the problem?. This effect occurs only when electric charges shift from their normal neutral position and is transferred from one object to another.. Students observe phenomena in which:. A balloon sticks to the wall after being rubbed on hair;. (A plastic bottle picks up small pieces of paper after being rubbed on cloths;. Etc. …). 1.
