F = e(v x B) is valid for:
Correct answer: B. Proton
- A. Electron
- B. Proton
- C. Neutron
- D. All of these options are correct
Explanation
Lorentz Force is only valid for protons, because the direction of conventional current is assumed to be the movement of positive particles.If electrons are being discussed a negative sign is added to the equation but as in the question there is no negative sign therefore it is only valid for protons.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
