1. Two very large plates are separated by a distance As. Each plate has a surface area of 1 m. The plates are connected by a battery, which puts 3 x 10-9 C on plate A and -3 x 10-9 C on plate B, as shown in the figure. A proton is released at rest from the inner edge of the positively charged plate. When it reaches the negatively charge plate, it has a speed of 3.7 x 104 m/s. (a) The battery provides a voltage difference between these two plates. What is the voltage of the battery? (b) What is the magnitude of the electric force experienced by the proton? (c) What is the distance between the two plates? A B 3 x 109 C 3 x 109 C As
