easy

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

A

$Y$-axis

B

$X$-axis

C

$Y$-axis only

D

None of these

Solution

(a) The electron reverses it’s direction. It can be done by covering semi-circular path in $x-z$ or $x-y$ plane.
