Question

Consider four charges arranged in a square of side length d as shown. Three of them have charge +|Q| and one has charge −|Q|.

a) Calculate the electric potential produced by these four charges at the center of the square, in terms of Q, d, and e0 (see image attached). Assume that the potential is zero infinitely far from the charges.

### Arrangement of Four Charges

Consider four charges arranged in a square of side length \( d \) as shown in the diagram. Three of these charges have a magnitude of \(+|Q|\) and one has a charge of \(-|Q|\).

#### Diagram Explanation

- The four charges are placed at the corners of a square.
- The length of each side of the square is denoted by \( d \).
- The charges are distributed as follows:
  - The top-left corner has a charge of \(+|Q|\).
  - The top-right corner also has a charge of \(+|Q|\).
  - The bottom-left corner has a charge of \(+|Q|\).
  - The bottom-right corner has a charge of \(-|Q|\).

The arrangement is such that three of the charges are positive, and one is negative, with the charges placed symmetrically around the center of the square. The interaction between these charges will result in a net electric force and potential at any point around them, which can be calculated using principles of electrostatics.

In the diagram, the distance \( d \) between adjacent charges is indicated by a blue bracket on the left side of the square.

**Problem Statement:**

Calculate the electric potential produced by these four charges at the center of the square, in terms of \( Q \), \( d \), and \( \epsilon_0 \). Assume that the potential is zero infinitely far from the charges.
