A beam of electrons passes underfected throgh unifromly perpendicular electric and magnetic fields. If the electric fiedl is swiched off, and the same magnetic field is mainted fiedl is maintetained the electrons move:

A beam of electrons passes undeflected through uniformly perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained then the electrons move:

A beam of electron passes undeflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained, the electrons move

A beam of electron passes undeflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained, the electrons move

A beam of electron posses undeflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off and the same magnetic field is maintained, the electrons move,

An the electron undeflected when passing perpen to mutually perpendicular electric and magnetic fields magnetic field is 8 Gauss and the electric field Vm^(-1) the velocity of the electron is

A charged particle moves undeflected in a region of crossed electric and magnetic fields. If the electric field is switched off, the particle has an initial acceleration a . If the magnetic field is switched off, instead of electric field, the particle will have an initial acceleration
