Maximum Electric Field of a Finite Line Charge

Question

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 which point on the y-axis is the magnitude of the electric field a maximum?

Accepted Answer

There is no finite maximum; the field diverges as $$y 	o 0$$

Answer

y = L

Answer

y = 0

Answer

y = L/\sqrt{2}
