You need to know the strength of the gravitational field where the electron is located. If it is in lab on Earth, the electron's weight is
W = m g
Set m*g = e*E and you get
E = g*(m/e)
The units will be N/C (or volts/meter) if e is 1.6*10^-19 Coulombs, and m is the electron mass, in kg
g = 9.8 m/s^2
W = m g
Set m*g = e*E and you get
E = g*(m/e)
The units will be N/C (or volts/meter) if e is 1.6*10^-19 Coulombs, and m is the electron mass, in kg
g = 9.8 m/s^2
