University Physics II – Notes and Exercises: Part 1: Electricity and Magnetism6Electric Forces and Fields1 Electric Forces and FieldsYour goal for this chapter is to understand the nature of electric forces and fields, and the superposition of electric forces and fields.Electric ForceExperiment shows that when rubber and fur are rubbed together, they develop the property of attracting each other. This kind of force that arises after objects are rubbed together is called electrical force. The change that occurred during the rubbing process that is responsible for this force is called charge. When another pair of rubber are rubbed together, the two rubbers (or the two furs) repel each other. This shows that there are two kinds of charges and that opposite charges attract and similar charges repel. Mathematically, these two different kind of charges are identified as positive and negative. The SI unit of measurement for charge is the Coulomb, abbreviated as C. Objects usually contain equal amounts of positive and negative charge; electrical forces between objects arise when those objects have net negative or positive charges.According to the Rutherford model of the atom, an atom consists of a nucleus with protons and neutrons with electrons revolving around. A neutron have no charge. An electron has a negative charge of -1.60 × 10 C. A proton has a positive charge numerically equal to that of the electron.-9According to the current understanding of charges, when rubber and fur are rubbed together, electrons are transferred from one to the other. The one that lost electrons becomes positively charged because it is losing negatively charged electrons, and the one that gained electrons becomes negatively charged because it is gaining negative charges.Charges are measured by a device called electroscope. An electroscope consists of a jar with a pair of gold leaves. When the gold leaves are brought into contact with a charged object, the two leaves acquire the same charges and repel each other forming a deflection angle between them. This deflection angle is proportional to the amount of charge; that is 4FRQVWDQWT where is charge and is the deflection Qθangle. The constant can be determined from a single pair of charge and deflection angle. And then the charge can be obtained by measuring the deflection angle.There are two ways by which an object can be charged, they are called conduction and induction.Download free eBooks at bookboon.com
