A free electron is suspended in an electric field near the surface of the Earth. Give an expression for the magnitude of this electric field assuming the electron is stationary, in terms of the mass me and charge e of the electron, and the gravitational acceleration g.  What is the magnitude of this electric field, in N/C, assuming the electron is stationary?  What does the small value for this field imply regarding the relative strength of the gravitational and electrostatic interaction?
