Electrostatics: Electric field, Gauss's law, Electric potential
Tipler 23-55
Gauss's law to find the electric field
Discuss conductors, what makes them special
Gauss's law really useful in situations with symmetry where E can be pulled out of
integral
Student should be able to draw electric field lines, might make sure of this by drawing
a couple of simpler situations
Think about field at large r. Does it make sense with respect to what you would respect
for a point charge with the same net charge as the object you are examining?
Tipler 24-17
Electric potential
Do the students understand how to calculate the potential difference between two points?
What does it mean that there is a potential difference between two points?
Make sure they are comfortable setting up and pursuing the problem without
"knowing" all the variables
The ratio of q/q' also needs a sign
Can the student draw the electric field lines?
Can the student draw lines of equipotential?
How is the potential related to the electric field?
