A monoenergetic electron of initial energy `18 keV` moving horizontally is subjected to a horizontal magnetic field of `0*4G` normal to its initial direction. Calculate the vertical deflection of the beam over a distance of `30cm`.  Mass of electron`=9*1xx10^(-31)kg`,  charge of electron `=1*6xx10^(-19)C`.
