Resumen
This article examined the average electrical force exerted by the Earth over an object, considering the Earth a conductive sphere of charge +Q. Spherical coordinate’s model was portrayed, and instantaneous electrical interaction (attraction over electrons minus repulsion over protons) was calculated, assuming electrons to be orbiting the corresponding protons. Integration of the instantaneous force over the orbital was performed, and following division by the orbital’s area outlined the average electrical force. Using equations derived from the model, it was found that the average electrical force acting over the object was consistent with a gravitational force. Theoretical and practical implications were discussed.
