Expert Answer:

Hello,
According to the lorentz force equation:
F = q ( v x B )
 
Hence if the direction of beam is from north to south, and magnetic field is directed downwards, then the direction of the term v x B will be towards East.
But as the beam consists of electrons, the charge will be negative and hence the net force will be in West direction.
