Assignment 18.] Concepts 1,2 1. There are very large numbers ofchargcd particles in most objects. Why, then, don't most objects exhibit static electricity? 2. Why do most objects tend to contain nearly equal numbers of positive and negative charges? Problem 14 1. Common static electricity involves charges ranging from nanocoulombs to microcoulornbs. (a) How many electrons are needed to form a charge of2.00nC (b) How many electrons must be removed from a neutral object to leave a net charge of 0.500yC? 2. If 1.80m 1020 electrons move through a pocket calculator during a full day's operation, how many coulombs of charge moved through it? 3. To start a car engine, the car battery moves 3.75X102' electrons through the starter motor. How many coulombs of charge were moved? 4. A certain lightning bolt moves 40.0 C of charge. How many fundamental units of charge Iqel is this
