after enteering through slits
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

A particle having a charge of 10 μC and mass 1 μg moves in a horizontal circle of radius 10 cm under the influence of a magnetic field of 0.1 T. When the particle is at a point P ,
a uniform electric field is switched on so that the particle starts moving along the tangent with uniform velocity. The electric field is ,
