Solve the all parts of given question:
Question: You make a capacitor by cutting the 15.5-cm-diameter bottoms out of two aluminum pie plates, separating them by 3.55mm , and connecting them across a 6.00-V battery.
Part A: What's the capacitance of your capacitor?
Part B: If you disconnect the battery and separate the plates to a distance of 3.50 cm without discharging them, what will be the potential difference between them?
Any help with steps will be great for above question.
