Electrons are released form rest inside a parallel plate capacitor at a distance, D, from a positively charged plate. The plate separation is d.
a) Draw the situation - include geometric dimensions and indicate the sign of charge on each plate.
b) Which plate will the electrons hit?
c) How fast is the electron moving when it hits the plate?
d) How much kinetic energy does the electron gain?
e) How much work does the electric field do on the electron?
f) If the electric field remains constant in spite of the electrons between the plates, what ultimately is doing work?
