Two conducting circular loops of radii $$R_1$$$\mathrm{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:
1. $$\frac{R^2_1}{R_2}$$
2. $$\frac{R^2_2}{R_1}$$
3. $$\frac{R_1}{R_2}$$
4. $$\frac{R_2}{R_1}$$

A long solenoid of diameter $$0.1$$ m has $$2 \times 10^4$$ turns per meter. At the center of the solenoid, a coil of $$100$$ turns and radius $$0.01$$ m is placed with its axis coinciding with the solenoid axis. The current in the solenoid reduces at a constant rate to $$0$$ A from $$4$$ A in $$0.05$$ s. If the resistance of the coil is $$10\pi^2~\Omega$$, then the total charge flowing through the coil during this time is:
1. $$16~\mu \text{C}$$
2. $$32~\mu \text{C}$$
3. $$16\pi~\mu \text{C}$$
4. $$32\pi~\mu \text{C}$$

Two coils have a mutual inductance $$0.005$$ H. The current changes in the first coil according to equation $$I=I_{0}sin\omega t$$ where $$I_{0}=2$$ A and $$\omega=100\pi$$ rad/s. The maximum value of emf in the second coil is:
1. $$4\pi$$ V
2. $$3\pi$$ V
3. $$2\pi$$ V
4. $$\pi$$ V
