An electron is placed in a vertical electric field directed upward and of intensity E=5v/m.

Question

Compare the weight of the electron to the electrostatic force to which it is submitted. Deduce.

Gravitational field strength: g=9.8m/s^2

Thanks.

Answer 1

Fe = Eq
q for an electron is 1.6e-19
Fg = mg
m for an electron is 9.11e-31
