Three identical particles, each possessing the mass m and charge +q, are placed at the corners of an equilateral triangle with side \[{{r}_{0}}.\] The particles are simultaneously set free and start flying apart symmetrically due to Coulomb?s repulsion foces. The work performed by Coulomb?s forces acting on to a very large distance is \[(\text{where }k=1/4\pi {{\varepsilon }_{0}}.)\]

A. \[\frac{3k{{q}^{2}}}{{{r}_{0}}}\]
B. \[\frac{k{{q}^{2}}}{{{r}_{0}}}\]
C. \[\frac{3k{{q}^{2}}}{2{{r}_{0}}}\]
D. \[\frac{k{{q}^{2}}}{2{{r}_{0}}}\]
Answer» C. \[\frac{3k{{q}^{2}}}{2{{r}_{0}}}\]
