Question: In which of the following scenarios is the magnetic force on a charged particle zero?

Options:

Correct Answer: Both 1 and 2

Solution:

The magnetic force on a charged particle is zero when it is at rest or when it moves parallel to the magnetic field.

In which of the following scenarios is the magnetic force on a charged particle zero?

In which of the following scenarios is the magnetic force on a charged particle zero?

Step 1: Understand that a charged particle can experience a magnetic force when it moves in a magnetic field.
Step 2: Know that the magnetic force depends on the speed and direction of the charged particle relative to the magnetic field.
Step 3: Recognize that if the charged particle is at rest (not moving), it does not experience any magnetic force.
Step 4: Learn that if the charged particle moves in the same direction as the magnetic field (parallel), the magnetic force is also zero.
Step 5: Conclude that the magnetic force is zero in two scenarios: when the particle is at rest or when it moves parallel to the magnetic field.

Magnetic Force on Charged Particles – The magnetic force on a charged particle is determined by its velocity and the magnetic field; it is zero when the particle is at rest or moving parallel to the magnetic field lines.
