Equipotential surface of a infinite plane?

[squirrelschaser]

Homework Statement

So the equipotential surface of a point charge is sphere with the charge in the center, and the equipotential surface of a infinite line is a cylinder with the line of charge as the axis. I was wondering what is the shape of the equipotential surface of a infinite plane?

The Attempt at a Solution

i) consider symmetries. ii) compute it iii) make an educated guess. iv) confirm guess by looking up what other sources say the potential of a infinite plane of charge looks like. Actually if you think really hard about i) you can skip the others. If you don't know what 'symmetries' is all about you and you can't compute it, skip the first options and just do the others. Variety of choices.
