Respuesta :

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

[tex]F=qvB sin \theta[/tex]

where

q is the magnitude of the charge

v is its velocity

B is the strength of the magnetic field

[tex]\theta[/tex] 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): [tex]sin 0^{\circ} = 0[/tex] ([tex]sin 180^{\circ}=0[/tex]
  • The force is maximum when the charge is moving perpendicular to the field, so when the angle between v and B is 90 degrees: [tex]sin 90^{\circ}=1[/tex]

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
