Electric and Magnetic Fields

    If a charged particle moves at a constant velocity in a straight line through a region of space, is the electric field and/or magnetic field in the region zero?

    If a charged particle moves at constant velocity, in a straight line, what is its acceleration? What, then is the force on it? What does that tell you about the electric and magnetic forces and fields?

    So, no forces?

    wait, according to the equation F=qvBsin theta .....can't there still be a magnetic force?

    oh wait nvm i got it lol

    what is another condition for constant velocity or it going in the straight line. if theres an electric field pulling it up and a magnetic field pulling it down...

    To sum it up,either both are absent,or present,but with perfectly balanced effects adding (as vectors) to zero.
