What is the force acting on a charge (q), moving with velocity (v) in a magnetic field(B)?

Answer»

Force acting on the particle,F = Bqv. In vector form, F = q (v × B) where, B is uniform magnetic field, v is velocity with particle which is moving. From this equation, it is clear that direction of force is perpendicular to the plane containing both v and B. In other words, force acts perpendicular to both v and B. When velocity becomes perpendicular to force, the path of the object becomes circular.

hi....but this is asking for ratio?
