Question

Suppose a magnetic field exists with the north pole at the top of the computer monitor and the south pole at the bottom of the monitor screen. If a positively charged particle entered the field moving from your face to the other side of the monitor screen, which way would the path of the particle bend?

a. left

b. right

c. up

d. down

e. none of these

Answer 1

The correct answer is:

b. right

Step-by-step explanation:

The direction in which a positively charged particle would experience a force due to a magnetic field is given by the right-hand rule. If you extend your right hand so that your thumb points in the direction of the particle's velocity (from your face to the other side of the monitor screen), and you extend your index finger in the direction of the magnetic field (from the bottom to the top of the monitor), then your middle finger will point in the direction of the force experienced by the particle.

In this scenario, if the north pole of the magnet is at the top of the computer monitor and the south pole is at the bottom, then the magnetic field lines would go from the north pole to the south pole. Given the motion of the positively charged particle and the direction of the magnetic field, the force on the particle would be to the right.

So, the correct answer is:

b. right
