A particle with electric charge 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?
1.Yes, you can.
2.No; the field might be perpendicular to the particle’s velocity.
3.No; the field might be parallel to the particle’s velocity.
4.No; the particle might need to have charge of the opposite sign to have a force exerted on it.
5.No; an observation of an object with electric charge gives no information about a magnetic field.

What is antimatter?
A) It consists of particles that are just like those of ordinary matter except with opposite properties, such as opposite charge. B) It is matter that we infer to be in space by its gravitational influence, but that we have not yet identified. C) It is a form of matter that has been hypothesized to exist but for which there is not yet any experimental evidence. D) It is the material that makes up a complete antiuniverse that is identical to our own except that it is made from antimatter instead of matter.
