The magnitude of force felt by a moving charge through a magnetic field would be least if the charge were

Question

Quizplus · Accepted Answer

The force on a moving charge in a magnetic field is given by the equation F = qvBsin(θ), where q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field. The force is least (zero) when sin(θ) = 0, which occurs when θ = 0° or 180°, meaning the charge is moving parallel or antiparallel to the magnetic field, as in options A and B.
