Electric Potential & Equipotentials

A regular hexagon of side 6 cm has a charge of 2 μC2\,\mu\text{C} at each of its vertices, what is the potential at the centre of the hexagon?

[14πε0=9×109\Bigg[\frac{1}{4\pi\varepsilon_0} = 9 \times 10^{9} SI unit ]\Bigg]

Show answer and solution

Answer: (b)

  1. In a regular hexagon each vertex is one side length from the centre: r=0.06 mr = 0.06\text{ m}.
  2. V=6×9×109×2×10−60.06=6×3×105V = 6 \times \frac{9 \times 10^{9} \times 2 \times 10^{-6}}{0.06} = 6 \times 3 \times 10^{5}
  3. V=1.8×106 VV = 1.8 \times 10^{6}\text{ V}
  4. So the answer is (b).
