A 5.00μF parallel-plate capacitor is connected to a 12.0 V battery. After the capacitor is fully charged, the battery is disconnected without loss of any charge on the plates. (a) A voltmeter is connected across the two plates without discharging them. What does it read? (b) what would the voltmeter read if (i) the plate separation was doubled; (ii) the radius of each plate were doubled but their separation was unchanged?
