An electron is traveling through a region between two metal plates in which there is a constant electric field of magnitude E along the y direction as sketched in Figure P17.46. This region has a total length L, and the electron has an initial speed v₀ along the x direction. 

(a) How long does it take the electron to travel the length of the plates? 

(b) What are the magnitude and direction of the electric force on the electron while it is between the plates? 

(c) What is the acceleration of the electron? 

(d) By what distance is the electron deflected (y) when it leaves the plates? 

(e) What is the final velocity of the electron? (Give the magnitude and direction or give the components of the velocity along x and y.)
