An electron is released from rest at the negative plate of a parallel plate capacitor. If the distance between the plates is 5 mm and the potential difference across the plates is 5 V, with what velocity does the electron hit the positive plate? (me = 9.1  10-31 kg, qe = 1.6  10-19 C.)

Question 2

To recharge a 12-V battery, a battery charger must move 3.6  105 C of charge from the negative to the positive terminal. What amount of work is done by the battery charger? How many kilowatt hours is this?
