is it possible for the magnetic force on a charge moving in a magnetic field to be zero? (b) is it possible for the electric force on a charge moving in an electric field to be zero? (c) is it possible for the resultant of the electric and magnetic forces on a charge moving simultaneously through both fields to be zero?



Answer :

a) Yes, provided that the speed is parallel to the magnetic field.

b) No, it is not possible electric field to be zero.

c) No. the magnetic force can be zero.

How do magnetic forces work?

Magnets, which can be used to repel or attract other things, exert a force known as magnetism. One of the fundamental forces of nature, electromagnetic, is one of the components of this potent physical phenomenon. A magnetic field is produced when electrically charged particles, which are present in all matter, move.

Briefing:

a)Yes, provided that the speed is parallel to the magnetic field.

b) No, the electric force acting on a charge travelling in an electric field cannot be zero since the electric field's amplitude and direction are independent of the motion or velocity of the charged particles.

c) No, the electric force cannot be zero because it is unaffected by the motion of the particles, but the magnetic force can be zero.
