1. The problem statement, all variables and given/known data 2. Relevant equations F=qE+qv x B 3. The attempt at a solution The electric and magnetic fields are parallel, so the magnetic force will be in the j direction and the electrostatic force will be in the k direction. If the magnetic force was acting alone it would be cyclotron motion but since the electrostatic force is acting too does this mean it is moving in a helical path? I'm having some difficulty thinking about where the electric field is pointing and how to draw it properly. Thanks for part b) I can find the acceleration using (qE)/m and plug into a distance equation but im not sure if that is what I'm being asked to do.
