An electron experiences a force of 12 mN in the positive x-direction in an electric field. What is the magnitude and direction of the electric field?

• Physics -

E field = Force/(electron charge)

Divide 12*10^-3 N by the electron charge in Coulombs.

You may need to look that up.

1 Newton per Coulomb is the same as 1 Volt per meter.
