Two equal charges q each are placed at a distance of ‘2 a’ and a third charge – 2q is placed at the midpoint. The potential energy of the system is
- \(\frac{q^{2}}{8 \pi \varepsilon_{0} a}\)
- \(\frac{6 q^{2}}{8 \pi \varepsilon_{0} a}\)
- \(-\frac{7 q^{2}}{8 \pi \varepsilon_{0} a}\)
- \(\frac{9 q^{2}}{8 \pi \varepsilon_{0} a}\)
Answer
(C) - 7 q^ 2 8 _ 0 a
