Electric field between positive planes

[novedevon]

Homework Statement

I'm looking at a problem where we have to draw the field lines above between and below two parallel planes going to infinity. Separated by distance D, both having equal positive surface charge density. 2. The attempt at a solution

I know that there will be perpendicular vectors out of the two surfaces. I'm confused on the between. will there be vectors meeting at a neutral zone in the middle? Other than that I'm not sure what is happening.

Thanks

Do you know what the field looks like for a single uniformly charged infinite plane looks like?
