An electron and a proton enter a magnetic field with equal velocities which one of them experiences more force:
Correct answer: C. Both experience same force
- A. Electron
- B. Proton
- C. Both experience same force
- D. Cannot be predicted
Explanation
F=q(V×B) F=qvBsin The formula infers that F∝v As both proton and electron have the same velocity they will experience the same value of force. As both have opposite charges, therefore the force being applied would be the same in magnitude but opposite in direction. In simple words both particles are deflected with the same force but in the direction opposite to each other.

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.
