A
particle of mass m and
charge (−q)
enters the region between the two charged plates initially moving
along x-axis
with speed vx (like
particle 1 in Fig. 1.33). The length of plate is L
and an uniform electric field E
is maintained between the plates.
Show that the vertical deflection of the particle at the far edge of
the plate is qEL2/
(2m).
Compare this motion with motion of a projectile in gravitational field discussed in Section 4.10 of Class XI Textbook of Physics.
