Question
**Description:**

**Figure Details:**
- The diagram displays two positive charges separated by a distance \(d = 3.00 \, \text{cm}\).
- The charge on the left is labeled \(Q = +2.00 \, \text{nC}\).
- The charge on the right is labeled \(2Q\), indicating it is double the charge of \(Q\), thus \(+4.00 \, \text{nC}\).
- Points A and B are located directly above \(Q\) and \(2Q\) respectively, forming a square with sides labeled \(d\).

**Tasks:**

**(a) Find the electric potential at point A.**
- A text box is provided for input.
- An error message indicates: "Your response differs from the correct answer by more than 100%."

**(b) Find the electric potential at point B.**
- A text box labeled with "kV" is provided for input.

**(c) Find the electric potential difference between B and A.**
- A text box labeled with "V" is provided for input.

**Instructions:**
Determine the electric potentials at points A and B due to the nearby charges using the formula for electric potential:

\[ V = \frac{kQ}{r} \]

where \( V \) is the electric potential, \( k \) is Coulomb’s constant \((8.99 \times 10^9 \, \text{Nm}^2/\text{C}^2)\), \( Q \) is the charge, and \( r \) is the distance from the charge.

Calculate the potential difference as the potential at B minus the potential at A:

\[ \Delta V = V_B - V_A \]
