An electron and proton are projected with the same velocity normal to a magnetic field. Which one will suffer greater deflection?
Correct answer: B. Electron
- A. Proton
- B. Electron
- C. Both will suffer greater deflection
- D. None
Explanation
Due to its smaller mass and the same charge-to-mass ratio as the proton, the electron will experience a greater deflection when projected with the same velocity normal to the magnetic field.

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.
