The particle with the smaller charge will experience a smaller force in a magnetic field because the magnetic force is directly proportional to the charge.
Step-by-step explanation:
To determine which of the two particles experiences a smaller force in a magnetic field, we must understand the basic relationship between magnetic force, charge, and velocity of a particle. The force (F) experienced by a charged particle moving in a magnetic field is given by the equation F = qvBsin(θ), where q is the charge of the particle, v is the velocity at which the particle is moving, B is the magnetic field strength, and θ is the angle between the direction of velocity and the magnetic field. Since the particles are moving parallel to each other at the same speed and assuming they are moving perpendicular to the magnetic field (since the force would be zero if they were moving parallel to the field), the angle is the same for both particles. Therefore, the particle with the smaller charge will experience a smaller magnetic force because the force is directly proportional to the charge (q).
The probable question can be: Two particles with different charges, but the same mass enter the same region that has a magnetic field B. The charges are travelling parallel to each other at the same speed. Which of the particles experiences the smaller force? Neither experiences a force. the particle with the smaller charge charge They experience the same force the particle with the larger charge
