Question
The force on a charged particle moving perpendicularly in an external magnetic field can be represented by the formula
- qvB
- qv/B
- qB/v
- q/vB
Hint:
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion
The correct answer is: qvB
The force on a charged particle moving in magnetic field is given by
F=qv×B
- When the velocity is perpendicular to the magnetic field, the magnetic force is perpendicular to both of them, and particle moves in circle with constant speed v.
