A charged particle moves through a magnetic field perpendicular to its direction. Then:
Q4mediummcqPhysicsAIEEE 20032026
A particle of charge moving with velocity along the -axis enters a region where a magnetic field of induction is along the -axis, and an electric field of magnitude is along the negative -axis. If the charged particle continues moving along the -axis, the magnitude of is:
Q5mediummcqPhysicsPhysics

An electron (mass and charge ) moving with speed ( = speed of light) is injected into a magnetic field of magnitude perpendicular to its direction of motion. We wish to apply a uniform electric field together with the magnetic field so that the electron does not deflect from its path. Then (speed of light ):
Q6easymcqPhysicsPhysics
A beam of electrons passes un-deflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained, the electrons move:
