There is an infinite straight chain of alternating charges q and -q. The distance between the two neighboring charges is equal to a. Find the interaction energy of any charge with all the other charges.

• A. \[-\frac{2{{q}^{2}}}{4\pi {{\varepsilon }_{0}}a}\]
• B. \[\frac{2{{q}^{2}}{{\log }_{e}}2}{4\pi {{\varepsilon }_{0}}a}\]
• C. \[-\frac{2{{q}^{2}}{{\log }_{e}}2}{4\pi {{\varepsilon }_{0}}a}\]
• D. Zero
