Homework Statement
Consider a magnetic field in the z direction. Two particles are moving perpendicular to this magnetic field, that is, they are both moving in the x-y plane. It is observed that the particles are both deflected by the magnetic field and they are deflected in opposite directions. Which of the following scenarios can account for this behavior?
True False they were initially moving in the same direction, but they have the same charge
True False they were initially moving in opposite directions, but they have the same charge
True False they were initially moving in opposite directions, but both are uncharged
True False they were initially moving in the same direction, but one is uncharged
True False they were initially moving in opposite directions, but they are oppositely charged
True False they were initially moving in the same direction, but they are oppositely charged
The Attempt at a Solution
My answers are in bold but the computer says they are wrong, here is my reasoning for my answers:
1) same charge particles repel one another
2) same as 1 so they will go in opposite directions
3) uncharged particles have no reaction
4) Again, one uncharged particle will have no reaction with a charged particle
5) Opposites will always attract one another, so they cannot go in opposite directions
6) same as 5, the opposites will pull each other together
Can any1 help me with what I am doing wrong?
