A free electron is suspended in an electric field near the
surface of the Earth.
A. 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.
B. What is the magnitude of this electric field, in N/C,
assuming the electron is stationary?
C. What does the small value for this field imply regarding the
relative strength of the gravitational and electrostatic
interaction?
