A beam of electrons passes undeflected through two mutually perpendicular electric and magnetic fields. E = 8kV /m and B = 2 × 10?3T . If the electric field is turned off and the same magnetic field is maintained, the electrons move in a circular path of radius 1.14cm. Determine the ratio of the electron charge to mass (qe/me).
