SUMMARY
Earth's electric field at its surface measures 1.0 x 10^2 N/C, directed towards the center of the planet. In comparison, the gravitational field also points towards the center but varies in strength with height, while the electric field remains relatively constant. The shape of the electric field is uniform near the surface, whereas the gravitational field decreases with altitude. The maximum mass that can be suspended by Earth's electric field, when considering a particle with an elementary charge, is determined by the relationship between electric force and gravitational force.
