### Electric Potential Calculation

#### Problem Description
The two charges in the figure below are separated by \( d = 3.50 \text{ cm} \). 
(Let \( q_1 = -19.0 \text{ nC} \) and \( q_2 = 26.5 \text{ nC} \)).

[Insert image of the charges configuration with the following details:

1. Diagram with an equilateral triangle where the vertices are labeled A, B, and the positions of charges \( q_1 \) and \( q_2 \).
2. Distance between charges denoted as \( d \).
3. Angle between lines connecting charges and point B labeled as 60.0°.
4. Position B is halfway between charges \( q_1 \) and \( q_2 \).]

#### Questions and Answers

**(a)** Find the electric potential at point A.

    Calculation Result:
    V_A = 1.927 kV ✅

**(b)** Find the electric potential at point B, which is halfway between the charges.

    Calculation Result:
    V_B = 3.596 kV ❌
    Note: Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. kV
