f=eVBsinθ
this is the formula for the force acting on a charged particle moving in a magnetic field
since the direction of velocity  (north to south, that is, from top to bottom )
and the magnetic field is same (downwards). the angle between them is zero
So there is no force acting on the electron beam.
