Question
An electron is moving along the positive X-axis. You want to apply a magnetic field for a short time so that the electron may reverse its direction and move parallel to the negative X-axis. This can be done by applying the magnetic field along
- Y-axis
- X-axis
- Y-axis only
- None of these
The correct answer is: Y-axis
The electron reverses it’s direction. It can be done by covering semi-circular path in x-z or x-y plane
