Problem 2.8 Purcell
3.
Problem 2.13, 2.14, 2.15 Purcell. Note 2.132.15 are very short math problems,
you should be able to do these rather quickly and without opening a book (if not,
work with your TA’s during their office hours for extra math help).
4.
Problem 2.29 Purcell
Note, don’t be mislead by what I might have alluded to in class. Treat each sphere
separately, then add, i.e., use superposition. These are NONconducting spheres.
5.
Find the potential of a uniformly charged spherical shell of radius R. In class I did
this by first calculating the electric field, then calculating a line integral. I would
like you to start with the charge density and NOT use the electric field at all.
Also, sketch the potential and the gradient of the potential as a function of
distance, take careful note what happens at surface of the sphere (this will help
This is the end of the preview.
