Electric Field Line Model, Gauss' Law
(Be sure you understand where and how each goal in each assignment applies to our homework,
discussion, lecture, and lab activities.)
Distinguish between electric field lines and electric field vectors, and show how they are
Sketch and describe the electric field line geometry for these charge distributions:
charge (+ or -), electric dipole (+ - pair), 2 like charges (+ or -), sphere of charge, long line of
charge, long cylinder of charge, flat sheet of charge.
Use symmetry properties of charge distributions to deduce the geometric properties of their
Use Gauss' Law to determine the strengths of electric fields in charge systems of sufficiently
high symmetry — spherical, cylindrical, and planar.
Use Gauss' law to locate electric charges.
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
Show that your algebraic and numerical results have the correct units.
Show that your algebraic and numerical results are physically reasonable.
