Question

Problem 10 A vertical
line of charge starts at y = -a and ends at y = 0. A charge Q is
uniformly distributed on this line. The point P_{1} is
located at the coordinate (x, 0), where x is a positive number.

(a) Draw a clear
picture of the situation, including the point P_{1}. Use
this picture to help explain if there are any symmetries you can
use to determine the electric field at point P_{1}.

(b) Find the x- and
y-components of the electric field at point P_{1}. If
either component is zero, be sure to make that clear.

(c) Determine the
angle of the electric field at P_{1} when x = 2a.

(d) Suppose you also
had a point charge Q. Is there a location where this point charge
can be placed so that the net electric field at the point
P_{1} (due to both the line charge and the point charge)
would be zero? If so, briefly explain, using words and equations,
how you would determine this location.

1.let us suppose that a uniform, thin line of charge Q stretches
from z=0 to z=L on theˆz-axis. This time calculate the electric
field produced by the line at a point r=xˆx forx>0. This point
is not equidistant from the two ends—does the electric field have
both an x and a z component there?
2. A charge q is placed at the point r=xx^ for the electric
field that you calculated in the previous problem.
