Which of the following is true about the Lorentz force?

It is same in magnitude for an alpha particle and beta particle travelling with same speed. It does not depend upon the nature of the electric or magnetic field. It depends on the velocity of the moving particle. For a particle at rest, the force is null.

It depends on the velocity of the moving particle.

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