# Electric Field of Perpendicular Charged Sheets

If we have two charged infinite sheets of charge density $\sigma$ and $-\sigma$ at right angles, how does the electric field look between them?

By using Gauss's law to get that the field from one sheet is $\vec{E}=\frac{\sigma}{2\epsilon_0}\vec{n}$ and superimposing these, I get that the field lines are diagonal lines. But doesn't the field lines always have to be perpendicular to a conductor?

• They only have to be perpendicular at the surface of the conductor. That's it. – ubuntu_noob Sep 1 '17 at 18:34
• Yeah but I think my calculations don't give perpendicular fields at the surfaces either. Sorry for the confusion. @ubuntu_noob – Jhonny Sep 2 '17 at 9:54
