Question
Transcribed Image Text:A finite rod of length L has total charge q,
distributed uniformly along its length. The rod
lies on the x-axis and is centered at the origin.
Thus one endpoint is located at (–L/2, 0), and
the other is located at (L/2, 0). Define the
electric potential to be zero at an infinite
distance away from the rod. Throughout this
problem, you may use the constant k in place
of the expression 1/(4€). What is V the
electric potential at point A (see the figure to
the right), located a distance d above the
midpoint of the rod on the y-axis?
