Solve the all parts of given question:
Question: A 3.2-cm-diameter parallel-plate capacitor has a 2.2mm spacing. The electric field strength inside the capacitor is 1.5 × 105 V/m.
Part A: What is the potential difference across the capacitor?
Part B: How much charge is on each plate?
I need help to find the potential difference across the capacitor and express your answer to two significant figures and include the appropriate units.
