Equal charges \[q\] are placed at the vertices \[A\] and \[B\] of an equilateral triangle \[ABC\] of side \[a\]. The magnitude of electric field at the point \[C\] is [MP PMT 1997]

\[\frac{q}{2\pi {{\varepsilon }_{0}}{{a}^{2}}}\]

\[\frac{q}{4\pi {{\varepsilon }_{0}}{{a}^{2}}}\]

\[\frac{\sqrt{2}\,q}{4\pi {{\varepsilon }_{0}}{{a}^{2}}}\]

\[\frac{\sqrt{3}\,q}{4\pi {{\varepsilon }_{0}}{{a}^{2}}}\]
