Four equal charges of value \(+\mathrm{Q}\) are placed at any four vertices of a regular hexagon of side 'a'. By suitably choosing the vertices, what can be the maximum possible magnitude of electric field at the centre of the hexagon?
(A) \(\frac{Q}{4 \pi \varepsilon_{0} a^{2}}\)
(B) \(\frac{\sqrt{2} Q}{4 \pi \varepsilon_{0} a^{2}}\)
(C) \(\frac{\sqrt{3} Q}{4 \pi \varepsilon_{0} a^{2}}\)
(D) \(\frac{2 Q}{4 \pi \varepsilon_{0} a^{2}}\)
Ans(C)
