(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle of charge q and mass m is travelling in the lab with velocity v in the x direction when it encounters a constant E-field in the y direction. State the non zero components of the Faraday tensor in the rest frame of the lab.

3. The attempt at a solution

I said

[tex]E=E_{x}i + E_{y}j + E_{z}k[/tex]

As the field is in the y direction

[tex]E=E_{y}j[/tex]

Thus I believe the faraday tensot to have 2 non-zero components.

[tex]F^{02}=-E_{y}[/tex] and [tex]F^{20}=+E_{y}[/tex]

This does not seem right as the next part of the question asks for the equations of motion for the particle which I get out as a load of 0's.

Am I missing a magnetic component, and if so, how do I get it?

Regards
