In Fig. 25-4 we show two large metal plates connected to a 120-V battery. Assume the plates to be in vacuum and to be much larger than shown. Find (a) E between the plates, (b) the force experienced by an electron between the plates, (c) the PEe lost by an electron as it moves from plate B to plate A, and (d) the speed of the electron released from plate B just before striking plate A.
