Two conducting circular loops of radii \(R_{1}\) and \(R_{2}\) are placed in the same plane with their centres coinciding. If \(R_{1}>>R_{2}\), the mutual inductance \(M\) between them will be directly proportional to:
A \(\frac{R_{1}}{R_{2}}\)
B \(\frac{R_{2}}{R_{1}}\)
c) \(\frac{R_{i}^{2}}{R_{2}}\)
(D) \(\frac{R_{2}^{2}}{R_{1}}\)
