What would be the electric potential of a point on the surface?

An electric field of approximately 100 V/m is often observed near the surface of Earth. If this were the field over the entire surface, what would be the electric potential of a point on the surface? (Set V=0 at infinity.)

I used the formula V=kQ/r where k=8.99x10^9 but I don't know the value of Q and r.

    E = V/r. r being the radius of the earth. Short answer is Gauss' law.
