If a charged particle goes unaccelerated in a region containing electric and magnetic fields,

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

A charged particle goes undeflected in a region containing uniform electric and magnetic field.It is not possible at all (vecupsilon="velocity of particle", vecE="uniform electric field", vecB="uniform magnetic field")

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

A charged particle is released from rest in a region of steady and uniform electric and magnetic fields which are parallel to each other . The particle will remove in a

A charge particle enters into a region containing uniform electric field (E) and uniform magnetic field (B) along x- axis and y-axis respectively.If it passes the region undeviated the velocity of charge particle is given by
