In the given fig. a charged particle of mass m
In the given fig. a charged particle of mass m, charge -q , and having low ( negligible ) speed enters the region between two plates of potential difference V and plate separation d, initioally headed directly toward the top plate . A uniform magnetic field of magnitude B is normal to the plane of the paper. Find the minimum value of magnetic field( B) such that the electron will not strike the top plate.

Electrons in a beam are accelerated from rest through a potential difference ΔV. The beam enters an experimental chamber through a small hole. As shown in Fig. 1.35 ,
In the given fig. a charged particle of mass m ,
the electron velocity vector lie within a narrow cone of half angle ϕ oriented along the beam axis. We wish to use a uniform magnetic field directed parallel to the axis to focus the beam ,
