Electrostatic Potential Energy

Six charges +q, $-$ q, +q, $-$ q, +q, and $-$ q are fixed at the corners of a hexagon of side d as shown in the figure. The work done in bringing a charge q0 to the centre of the hexagon from infinity is ( $\varepsilon_0$ - permittivity of free space)

Show answer and solution

Answer: (b)

All six charges are at distance $d$ from the centre.
$V_{centre} = \dfrac{k}{d}(q - q + q - q + q - q) = 0$
$W = q_0(V_{centre} - V_\infty) = 0$
So the answer is (b) zero.
