OK. In my book it says that for "any point" the Electric Field Magnitude for a Infinite sheet of charge with uniform charge per unit area is [tex] \frac{\sigma}{2\epsilon_{0}} [/tex], and for a wire of infinite length the Electric Field Magnitude is [tex] E = \frac{\lambda}{2\pi\epsilon_{0}r} [/tex] where r is the distance from the wire.
Why is E for the infinite wire dependent on distance, but not the distance for the infinite sheet. Wouldn't the E get smaller the farther away from the infinite sheet? This is not a HW question.
