In the formula F=q(vxB):
Correct answer: D. F must be perpendicular to both V and B
- A. F must be perpendicular to V but not necessarily to B
- B. F must be perpendicular to /3. but not necessarily to V
- C. V must be perpendicular to 173. but not necessarily to F
- D. F must be perpendicular to both V and B
Explanation
F=e(VxB)F = qv × B. The force F is perpendicular to the direction of the magnetic field B. It also is perpendicular to the direction of the velocity v.

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.
