Homework Help: Special Relativity - Lorentz Force Law

  1. Nov 17, 2009 #1
    1. The problem statement, all variables and given/known data

    Show that the 4-force law: F_u=q/c E_{uv}U^v leads to the usual Lorentz force law.

    2. Relevant equations

    F = E + v x B.

    3. The attempt at a solution

    What's U?

    Uv looks like a four velocity with a raised index. What is Euv?
