2. A 20 micro-Farad parallel plate capacitor is connected to a 10 V battery. a. How much charge is on the capacitor? (3 points) b With the capacitor still connected to the battery, the plates are brought closer together such that they are half the distance apart that they were in part a. Now how much charge is on the capacitor? Explain or show work. If you can't calculate a number explain why the charge increases, decreases or stays the same. (3 points)C. Now, with the capacitor back the way it was in part a, the capacitor is disconnected from the battery. Next, the plates are brought closer together such that they are half the distance apart that they were in part a. Now how much charge is on the capacitor? Explain or show work. If you can't calculate a number explain why the charge increases, decreases or stays the same. (3 points)d. Is the voltage across the capacitor in part c (after the plates are moved closer together) still 10V, or is it higher, or is it lower? Explain. (3 points)
