Homework Statement
1. If a charged particle moves in a straight line through some region of space, can you say that the
magnetic field in that region is zero? Explain.
2. How can the motion of a charged particle be used to distinguish between an electric field and a
magnetic field?
3. If a cosmic ray proton approaches the Earth from outer space along a line toward the center of the
Earth that lies in the plane of the equator, in what direction will it be deflected by the Earth’s magnetic
field? What about an electron? A neutron?
Homework Equations
1. If a charged particle moves in a straight line though space, you can say that the magnetic field in the region is zero. This is because the cosine of 0 is 0, so the magnetic field is zero. The force is in the same direction as the velocity which creates an angle of 0 degrees. Thus, there is no force.
2. I don't understand this at all. My professor was saying something about affecting the particles e field in a straight line versus curving for the e- field.
3. I don't know where to start on this one to be honest.
