Why does kinetic energy of a charged particle remains constant if velocity and force are perpendicular to each oher at all times?

Expert Answer:

The force is given by a direction which is perpendicular to the magnetic field and the velocity of the particle moving in that field.
 
Kinetic energy is dependent on the velocity of the particle, and hence it remains constant no matter how the force acts on the particle.
