Two conducting circular loops of radii $R_1$ and $\mathrm{R}_2$ 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

$\frac{\mathrm{R}_1}{\mathrm{R}_2}$

$\frac{R_2}{R_1}$

$\frac{\mathrm{R}_1^2}{\mathrm{R}_2}$

$\frac{R_2^2}{R_1}$
