A charged particle is fired into a region of space where the electric field is zero. It moves in a straight line. Can you conclude that the magnetic field in that region is zero? Question 9Select one: A. No; observation of an object with charge gives no information about a magnetic field. B. No; the field might be perpendicular to the particle's velocity. C. No; the particle might need to have charge of the opposite sign to have a force exerted on it. D. Yes, you can. E. No; the field might be parallel to the particle's velocity.
