Electrons are initially traveling at 2.40×106 m/s in the horizontal direction. They enter a region between two charged plates of length 2.00 cm and experience an acceleration of 4.00×1014 m/s2 vertically upward. Find: (a) the vertical position as they leave the region between the plates; (b) the angle at which they emerge from between the plates
a) The electron travels the length of the plate with velocity in a time .
( no horizontal acceleration )
In this time, the electron moves through a vertical distance , with vertical acceleration
( initial vertical velocity is zero, )
Vertical position as the electron leaves the region between the plates is
-------------
b)
When electron emerges from the region,
Angle at which the electron emerges from between the plates is
-------------------
