A ring of radius \( R \) is having two charges \( q \) and \( 2 q \) distributed on its two half parts. The electric potential at a point on its axis at a distance of \( 2 \sqrt{2} R \) from its centre is \( \left(k=\frac{1}{4 \pi \varepsilon_{0}}\right) \)
(a) \( \frac{3 k q}{R} \)
(b) \( \frac{k q}{3 R} \)
(c) \( \frac{k q}{R} \)
(d) \( \frac{k q}{\sqrt{3} R} \)
