# The net charge of Earth

Shouldn't the earth have an over all small positive net charge? Cosmic rays in the form of light or high energy particles can ionize atoms, when that happens the electron and the positive ion recoils and the electron gets a whole lot more velocity than the positive ion. Meaning the electron had an easier time escaping earth, and the ones that don't will have a lower average density because of higher orbits, of this causes earth to have an over all positive charge, then the electric field grows until this effect is balanced with the electric fields potential, so that the charges are as easily ejected in the form of ions and the form of electrons. Wouldn't this mean that depending on the background ionizing radiation the earth will have a certain equilibrium positive charge?
