an electron of mass m
Bainbridge’s mass spectrometer separates ion having the same velocity. The ions, after enteering through slits, S1 and S2, pass through a velocity selector composed of an electric field produced by the charged plates P and P’ and a magnetic field B perpendicular to electric field and the ion path.Thew ions that then pass undeviated through the crossed E 1 and B fields enter into a region where a second magnetic field B exists, where they are made to follow circular path. A photographic plate ( or a modern detector) registors their arrival. If r is the radius of the circular orbit , then specific charge qm of ion is

In the below fig, an electron of mass m, charge -e, and low (negligible )speed enters the region between two polates of potential difference V and plate seperation d, initially headed directly toward the top plate. A uniform magnectic field of magnitude B is normal to the plane of the fig. find the minimum value of B such that the electron will not strike the top plate.
