Two parallel conducting plates of a capacitor of capacitance C containing charges Q and -2Q at a distance d apart. Find out potential difference between the plates of capacitors.

Explanation

To find the potential difference between two parallel conducting plates of a capacitor with capacitance \( C \), containing charges \( Q \) and \( -2Q \), and separated by a distance \( d \), we can follow these steps:

### Step 1: Understand the Charges on the Plates
Given that one plate has a charge \( Q \) and the other has a charge \( -2Q \), we can denote the charges as follows:
- Plate 1: Charge \( Q \)
- Plate 2: Charge \( -2Q \)

### Step 2: Calculate the Electric Field Between the Plates
