To determine

The correct option for the statement “A magnetic force can act on an electron even when it”.

Answer to Problem 3RAT

The correct option for the statement “A magnetic force can act on an electron even when it” is option (d).

Explanation of Solution

A field around magnetic particles where a charged particle encounters a force is known as a magnetic field. This can be attractive in mature or repulsive. The magnetic force acts on an electron when it is moving in the field. It means that the magnetic force will act on the electron, only when it is in motion inside the magnetic field. Moreover, the electron's direction should not be parallel to the direction of the magnetic field lines. If the particle moves parallel to the magnetic field lines, no force will be acting over it. Force will only act on the electron when it moves at any angle to the field line. The greatest amount of force will be experienced when it moves right angle to the field lines.

Conclusion:

Therefore the correct option for the statement “A magnetic force can act on an electron even when it” is option (d).
