APFIVE Maximum Electric Field of a Finite Line Charge
A finite line charge of length 2L and uniform linear charge density $$\lambda$$ is centered at the origin and aligned with the x-axis. At what point on the y-axis will the electric field be maximum?
A
y = L/\sqrt{2}
B
There is no finite maximum; the field diverges as $$y \to 0$$
C
y = 0
D
y = L
