Which of the following is true about the Lorentz force?

It depends on the velocity of the moving particle.

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

1. It is NOT same in magnitude for an alpha particle and beta particle as their charges are different.
2. It does depends upon the nature of the electric or magnetic field.
3. For a particle at rest, the force is NOT null.
