A charged particle moves along a circle under the action of possible constant electric and magnetic fields. Possible case is

A changed particle mvoes along a circle under the action of possible constant electric and magnetic fields. Possible case is

A charged particle moving in an electric field

A charged particle goes undeflected in a region containing electric and magnetic field. It is possible that

A charged particle goes undeflected in a region containing electric and magnetic field. It is possible that

A charged paricle goes undeflected in a region containing electric and magnetic field. It is possible that

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
