a positive charge is moving to the right and experiences a vertical upward magnetic force. In which direction is the magnetic field?
to the right
to the left
out of the page
into the page
upward
v X B. Right hand rule. Into the page.
To determine the direction of the magnetic field, we can apply the right-hand rule. The right-hand rule states that if a positive charge is moving in a specific direction and experiences a magnetic force in another direction, you can determine the direction of the magnetic field by pointing your right thumb in the direction of the positive charge's motion and curling your fingers towards the direction of the magnetic force.
In this case, since the positive charge is moving to the right and experiencing an upward magnetic force, if you point your right thumb to the right, and curl your fingers upwards, your fingers will be pointing out of the page.
Therefore, the direction of the magnetic field is out of the page.
To determine the direction of the magnetic field, we can use the right-hand rule. According to this rule, if a positive charge moving in a specific direction experiences an upward magnetic force, we can use our right hand to determine the direction of the magnetic field.
1. Extend your right-hand thumb in the direction of the positive charge's velocity, which in this case is to the right.
2. Curl your fingers towards the upward magnetic force.
If you do this, you will realize that your fingers point out of the screen or page. Therefore, the direction of the magnetic field is out of the page.
