Two large parallel plates are placed horizontally with respect to each other and are then connected to a 100-V battery. If the distance between the plates is 1 cm, the uniform electric field between the plates is 104 N/C in the upward direction as shown by the vectors in the figure. If the electron is released from rest at the upper plate, calculate: i. kinetic energy of the electron after traveling 1 cm to the lower plate, and ii. the time required for it to travel this distance.
