# Physics: Deflection of particles by a magnetic field. Select true or false statements.

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? Select True or False for the following:

True False they were initially moving in opposite directions, but they have the same charge

True False they were initially moving in the same direction, but one is uncharged

True False they were initially moving in opposite directions, but both are uncharged

True False they were initially moving in the same direction, but they are oppositely charged

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 are oppositely charged

#### Solution Preview

It is given that, the magnetic field is in the z direction. now let us see the possibilities.

1) True False they were initially moving in opposite directions, but they have the same charge

This is True. cause, the force can be opposite in direction velocity vector changes the sign.

2) True False they were initially ...
