Problem 4

If you have charged an electroscope by contact with a positively charged object, describe how you could use it to determine the charge of other objects. Specifically, what would the leaves of the electroscope do if other charged objects were brought near its knob?

Chapter 6 Core concept Electric and magnetic fields interact and can produce forces 1. Electric charge (q) unit: coulomb (c)- see slide 2 The kind of charge- positive-proton Negative-electron  Unit of charge= coulomb o Equivalent to charge of 6.24x10^18 o Metric unit of charge  Electron charge o Fundamental charge o Smallest seen in nature o Quantity of charge and the number of electrons An electron charge can be produced by: friction, contact, induction/polarization Slide 3:  Charges in matter  Inseparable property of certain particles  Electrons: negative electric charge  Protons: positive electric charge  Charge interaction  Electric force  “like charges repel; unlike charges attract”  Ions: non- zero net charge from loss/gain of electrons Slide 11: Coulumb’s law  Relationship giving force between two charges  Similar to Newton’s law of gravitation  K versus G implies gravity weaker Equation 6.2 Charge interaction: like charges repel, unlike attracts [6.1] Quality of charge= (# of electrons) (electron charge) q=ne e= 1.6x10^-19 C Example: 1c = n(1.6x10^-19 C) 1.6x10^-19c 1.6x10^-19c n= 1 1.6x10^-19 n=6.24x10^18 I-clicker questions 1. In an experiment in the late 1800’s, J.J. Thomson discovered that all matter contained negatively charged particles.
