Deriving the trajectory of the particle

[Tuugii]

Homework Statement

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.

Homework Equations

Lorentz force: F=q(E+v*B)

The Attempt at a Solution

Please give some hints. :)

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?

 

[Tuugii]

3rd law, and the sum is 0
