A particle of mass m and charge q initially at rest is accelerated by a potential difference V to a velocity v directed towards south The particle enters a region in which both a magnetic field B and an electric field E exist The magnetic field is uniform and is directed eastward and the electric field is in the vertically downward direction The particle is found to travel in this region of electric and magnetic field without being deflected from its original trajectory One can conclude that A V B V mE2 2qB 2mE qB E C V qB
