2009E2 (modified) Electrons created at the filament at the left end of the tube represented above are accelerated through a voltage V0 and exit the tube. The electrons then move with constant speed to the right, as shown, before entering a region in which there is a uniform electric field between two parallel plates separated by a distance D . The electrons enter the field at point P , which is a distance y0 from the bottom plate, and are deflected toward that plate. Express your answers to the following in terms of V0,D,y0, and fundamental constants.
a. Calculate the speed of the electrons as they exit the tube.
b. i. Calculate the magnitude of the electric field required to cause the electrons to land the distance y0 from the edge of the plate.
ii. Indicate the direction of the electric field.
___ To the left ___ To the right
___ Toward the top of the page ___ Toward the bottom of the page
___ Into the page ___ Out of the page
Justify your answer.
c. Calculate the potential difference between the two plates required to produce the electric field determined in part b.
