If 3 charges are placed at the vertices of equilateral triangle of charge ?q? each. What is the net potential energy, if the side of equilateral \[\Delta \] is l cm [AIEEE 2002]

\[\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{4{{q}^{2}}}{l}\]

\[\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{q}^{2}}}{l}\]

\[\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2{{q}^{2}}}{l}\]

\[\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{3{{q}^{2}}}{l}\]
