The potential at the centroid of an equilateral triangle of side r√3 due to three equal positive point charges each of value q and placed at the vertices of the triangle would be:

• A. \(\frac{q}{2\pi {{\epsilon }_{0}}r}\)
• B. \(\frac{\sqrt{3}q}{8\pi {{\epsilon }_{0}}r}\)
• C. \(\frac{3q}{4\pi {{\epsilon }_{0}}r}\)
• D. Zero
