Physics 2213
Homework #1
Spring 2009
Read:
Chapter 21:
intro., sections 21.14, 21.5 (thru p. 729),
21.7 (Mostly for conceptual enrichment, rather than quantitative mastery.
Can you do Example 21.15 on p. 738 by the common denominator
method, rather than by using power series?)
Learning Goals:
(Be sure you understand where and how each goal in each assignment applies to our homework,
discussion, lecture, and lab activities.)
*
Use Coulomb's Law to determine the magnitude and direction of the electric force between
any 2 point charges.
*
Determine the magnitude, direction, and components of the net electric force on any
specified point charge due to a collection of other point charges using Coulomb's law and
the Superposition Principle applied to electric force vectors.
*
Explain how a neutral object can become electrically polarized by a nearby charged object.
*
Explain how a neutral object can experience a net electric force due to a charged object.
*
Distinguish between electric force and electric field, and explain how they are related.
*
Determine and sketch the electric field vector geometry by vector constructions based on the
Superposition Principle for these charge distributions:
point charge (+ or ), electric dipole
(+  pair), 2 like charges (both + or ).
*
Conceptually translate an equation for an electric field as a function of position into a graph
(without doing detailed numerical calculations).
*
Determine the asymptotic limiting forms of the electric field as a function of position at small
and large distances from a distribution of electric charge(s), and explain what these forms
