Homework #2
Due:
Monday 15 October 2007
1)
Do problem P.232 in Cheng.
2)
An infinite tube of radius
a
carries a surface charge density
s
ρ
[C/m
P
2
P
], and is coaxial
with the
z
axis.
Using Gauss' law and a convenient coordinate system, find the
electric field both inside and outside the tube.
Also find the electrostatic potential
assuming a zeroreference at
ra
=
.
3)
Do problem P.37 in Cheng.
It is probably easier to first find the potential and
compute the field from that.
Exploit the symmetry of the problem to simplify things.
4)
Do problem P.321 in Cheng.
5)
Do problem P.328 in Cheng.
6)
Do problem P.335 in Cheng.
Assume that the reference potential is zero at infinity.
7)
An array of positivelycharged ions fills the region
between two large conducting plates as shown below.
The plates have a crosssectional area
