HW 1 solutions Point Charge in One Dimension A point charge q1 = -3.5 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57

Electricity is the force that holds together the molecules and atoms of all substances. The type of electricity that is most familiar to us is electrical current. This is the flow of electrical charges through a substance called a conductor such as a metal wire. This flow happens beacuse some of the negatively charge electrons circling the nuclei of the conductor’s are held loosely. The electrons can move from one atom to the next‚ producing and electrical current. Electricity has become something we

each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge &#8211; positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel each other. Pieces of matter

Ch.9.1 – Types of Electric Charge * Static electricity : static cling of clothes out of dryer; lightning; * Walk across carpet and touch get a shock touching metal doorknob – friction of shoes against carpet cause you acquire static electric charge * Static chargeelectric charge at rest‚ stays on and eventually discharged or lost to other objects/air * Discharge – remove excess static charge so the object is neutral * Static charge last long when air is dry * Electrostatics

Electric Charge Lab John Doe Physics 1130 Oct 26th‚ 2010 Objective In this lab we will investigate some properties of electric charge‚ conductors‚ and insulators using everyday objects. Theory A charged object is any object that has an excess of negative or positive charge. Most objects are neutrally charged and we don’t normally experience their charge properties. Rubbing objects together and transferring some charge from one to the other is one way to create charged objects. Like charges

제출 2010년 3월 19일 (금) C319 1. Three point charges Q1  9 C ‚ Q2  4 C ‚ Q3  36 C are arranged on a straight line. The distance between Q1 and Q3 is 9cm. It is claimed that a location can be selected for Q2 such that each charge will experience a zero force. Find this location. 2. A line charge of uniform charge density l forms a circle of radius b that lies in the xy-plane in air with its center at the origin.  a) Find the electric field intensity E at the point (0‚ 0‚ h)

Electric Charge and Electric Field:-> 1. Electric Charge Electric charge is a fundamental property like mass‚ length etc associated with elementary particles for example electron‚ proton and many more. Electric charge is the property responsible for electric forces which acts between nucleus and electron to bind the atom together. Charges are of two kinds (i) negative charge (ii) positive charge Electrons are negatively charged particles and protons‚ of which nucleus is made of‚

produced? Have you ever noticed how your hair stands straight and stiff when you comb it vigorously on a dry‚ cold day? Or how difficult it is to remove dust particles from your comb? Your hair and the comb become charged by rubbing. This stationary electric charge is described as static electricity. Activity 1. Rub a plastic sheet with flannel and then hold the plastic sheet near Styrofoam bits. What do you observe? From the observations made‚ you can conclude that rubbing produces static electricity on
