Find the electric potential function Φ(x) at a point that is located at x > 0 from an infinite uniform planar sheet of charge density rhos0 located at x = 0, when the reference point is located at a distance x0 > 0 from the sheet and the potential at the reference point is zero. Do this by integrating the electric field. Describe the surfaces on which the potential is constant. Then answer the following questions:

Is it possible to locate the reference point at x0 = [infinity]? If not, why not?
