Verbatim question for GR8677 #25
Electromagnetism}Lorentz Force

Recall the Lorentz Force, \vec{F}=q(\vec{E}+\vec{v}\times\vec{B}).

\vec{E} and \vec{B} are parallel. The particle is released from rest, so the Electric force would propel it. The resulting velocity would be parallel to the electric field, but since the magnetic field is also parallel to that, there would be no magnetic force contribution. The particle thus goes in a straight line.
