**Title: Electric Potential Calculation for Point Charges**

**Introduction:**

The figure below illustrates a scenario involving two point charges. These charges are separated by a distance, and we are interested in finding the electric potential at specific points in relation to these charges.

**Description of the Figure:**

- The figure is an equilateral triangle with three points: \(A\), \(B\), and the points where the charges are located (\(q_1\) and \(q_2\)).
- The side length of the triangle is denoted as \(d = 4.00 \, \text{cm}\).
- The angle at point \(B\) is \(60.0^\circ\).
- Charge \(q_1 = -20.0 \, \text{nC}\) is located on the left.
- Charge \(q_2 = 25.0 \, \text{nC}\) is located on the right.
- Point \(A\) is at the top vertex of the triangle.

**Objective:**

(a) **Find the electric potential at point \(A\):**

- Your response was more than 100% different from the correct answer, suggesting a major calculation error.

(b) **Find the electric potential at point \(B\),** which is situated halfway between the charges on the horizontal side of the triangle.

**Explanation of Graphs or Diagrams:**

- The diagram includes vectors indicating the direction from each charge to point \(A\) and \(B\).
- It shows the geometric relationship between the charges and points of interest within the triangle.
  
**Steps for Calculation:**

1. **Calculate the Electric Potential at Point \(A\):**
   - Use the formula for electric potential due to a point charge \( V = \frac{k \cdot q}{r} \), where \( k \) is Coulomb's constant, \( q \) is the charge, and \( r \) is the distance from the point of interest to the charge.
   - Consider contributions from both \( q_1 \) and \( q_2 \).

2. **Calculate the Electric Potential at Point \(B\):**
   - Follow the same formula, remembering to account for the distances from \( B \) to each charge \( q_1 \) and \( q_2 \).

This problem provides a practical application of the principles of electric potential and the effects of charge distribution in electro
