A stream of electrons moving with a velocity of `3xx10^(7) ms^(-1)` is deflected by 2 mm in traversing a distance of 0.1 m in a uniform electric field of strength `18 Vm^(-1)` in Fig. 1.42. An electron enters the field symmetrically between the plates with a speed `upsilon_(0)`. The length of each plate is l. Find the angle of deviation of the bath of the electron as it comes out of the field.
