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

Solutions

Expert Solution

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

-------------

When electron emerges from the region,

Angle at which the electron emerges from between the plates is
