Homework Help: Deriving the trajectory of the particle

  1. Jan 27, 2008 #1
    1. The problem statement, all variables and given/known data
    There is a uniform electric field E, and a uniform magnetic field B in space. A particle of mass m, and charge q, at the origin is released from rest at t=0. The only acting force on the body is the Lorentz force. Derive the trajectory of the particle for t>=0.


    2. Relevant equations
    Lorentz force: F=q(E+v*B)


    3. The attempt at a solution

    Please give some hints. :)

    thanks,
    T

    Hint: sum of forces equals what?

    thanks

    forces? it says the only force is Lorentz one....

    hey I am totally newbie to EM. :P

    OK, let me rephrase the question: which of Newtons laws is relevant here?

    3rd law, and the sum is 0
