An electron enters the region of a uniform electric field between two oppositely charged parallel plates as shown, with an initial velocity of 3 x 106 m/s. The electric field between the plates is measured to be E = 200N/C. The horizontal length of the plates is 10cm.
a. Find the acceleration of the electron while it is in the electric field.
b. How long does it take the electron to travel the length of the plates and
leave the field?
