If identical charges \[(-q)\] are placed at each corner of a cube of side b, then electric potential energy of charge \[(+q)\] which is placed at centre of the cube will be [CBSE PMT 2002]

\[\frac{8\sqrt{2}{{q}^{2}}}{4\pi {{\varepsilon }_{0}}b}\]

\[\frac{-8\sqrt{2}{{q}^{2}}}{\pi {{\varepsilon }_{0}}b}\]

\[\frac{-4\sqrt{2}{{q}^{2}}}{\pi {{\varepsilon }_{0}}b}\]

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