In the formula F= q (v×B)
Correct answer: C. **F must be perpendicular to both v and B**
- A. **F must be perpendicular to v but not necessarily to B**
- B. **v must be perpendicular to B but not necessarily to F**
- C. **F must be perpendicular to both v and B**
- D. All three vectors must be mutually perpendicular
Explanation
Understanding the Formula F = q(v × B)The formula \( F = q(v \times B) \) represents the force \( F \) experienced by a charged particle moving with velocity \( v \) in a magnetic field \( B \), where \( q \) is the charge of the particle. This statement is correct. The force \( F \) is indeed perpendicular to both the velocity \( v \) and the magnetic field \( B \) according to the formula given.

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.
