A charged nonconducting rod has a length L of 2.0 m and a cross-sectional area A of 8.0
cm?; it is placed along the positive side of an x axis with one end at the origin. The
volume charge density p is the charge per unit volume, with the units of coulomb per
cubic meter.
a) How many excess electrons are on the rod if the rod's volume charge density pu is
uniform with a value of –10 µC/m³? How does that compare to the total number of
electrons you would estimate would be in the rod? (By compare, just a ballpark estimate-
to within several orders of magnitude, factors of ten).
b) What is an expression for the number of excess electrons on the rod if the rod's
volume charge is nonuniform and is given instead by pN=ax³ where a is a constant?
c) What value of a is necessary for the rod in part b to have the same number of excess
electrons as the rod in part a)?
