Using Right Hand Rule & Lorentz Force Law to Find Electric Field Direction

[grscott_2000]

I have a question regarding electrons in an electric and magnetic field and I need to apply Lorentz force law to find the direction in which the electric field is pointing.

Would someone be good enough to explain how the right hand rule applies in this situation? I think I might be getting confused with positive and negative charges and the effects they have on direction.

Also, does anyone know any resource on the net that give worked examples of Lorentz and the right hand rule so that I can work through them and see what is happening?

Many thanks
