In the formula F=q (vxB).
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 B
- C. F must be perpendicular to both v and B
- D. All three vectors must be mutually perpendicula
Explanation
Option B is correct.In vector product, all three vectors are mutually perpendicular. Yes, in the formula F = q(v x B), F must be perpendicular to both v and B, but charge is not a vector.The direction of the magnetic force is given by the cross product of the velocity and the magnetic field. The cross product of two vectors is a vector that is perpendicular to both vectors

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.

the magnitude of force on a moving charge is not zero when the angle between the velocity of the charge carrier and the magnetic field is zero. The magnetic force on a charged particle is given by the following equation: F = qvB sin θ where: F is the magnetic force (N) q is the charge of the particle (C) v is the velocity of the particle (m/s) B is the magnetic field strength (T) θ is the angle between the direction of the velocity and the direction of the magnetic field (°) When the angle between the velocity and the magnetic field is zero, then the sine of the angle is also zero. sin 0° = 0 The magnetic force is then zero. Therefore, the magnitude of the force on a moving charge is not zero when the angle between the velocity of the charge carrier and the magnetic field is zero.
