Question

due to motion of charge ,its magnitude​

Answer 1

Answer:

Since their movement is always perpendicular to the force, magnetic forces due no work and the particle's velocity stays constant. Since the force is F = qvB in a constant magnetic field, a charged particle feels a force of constant magnitude always directed perpendicular to its motion.

Answer 2

Due to motion of charge, its magnitude​:

Step-by-step explanation:

• It will accelerate if it is travelling in the opposite direction.
• If a charged particle moves between parallel electric plates with a velocity that is initially parallel to the plates,
• it will be deflected toward the plate with the opposite charge, increasing the magnitude of its velocity vector.
• Magnetic forces do no work and the particle's velocity remains constant because their movement is always perpendicular to the force.
• In a constant magnetic field, the force is F = qvB,
• therefore a charged particle experiences a force of constant magnitude that is constantly directed perpendicular to its motion.
