3. What is the magnitude of the electric field strength E such that an electron, when placed in the field, would experience an electrical force equal to its weight? What electric field strength E is required if the electron is replaced by a proton

E=mg/e where e is the charge on an electron
Proton? reverse the sign, use m as mass of proton.
