The charge experiences no magnetic force when it is moving to the left or to the right
Explanation:
The force experienced by a charge moving in a magnetic field is given by the equation
where
q is the magnitude of the charge
v is its velocity
B is the strength of the magnetic field
is the angle between the directions of v and B
From the equation, we observe that:
- The force is zero when the charge is moving parallel (or anti-parallel) to the field, so when the angle between v and B is zero (or 180 degrees):
(
- The force is maximum when the charge is moving perpendicular to the field, so when the angle between v and B is 90 degrees:
From the first observation, we can say therefore that the charge in the problem will experience no magnetic force when it is moving parallel (or anti-parallel) to the field. Since the magnetic field points to the left, this means that the charge will experience no force when it is moving in one of the following directions:
- To the left
- To the right
