i. A vertical iron rod has a coil of wire wound over it at the bottom end. An alternating current flows in the coil. The rod goes through a conducting ring as shown in the figure. The ring can float at a certain height above the coil. ii. In the above situation, a current is induced in the ring which interacts with the horizontal component of the magnetic field to produce an average force in the upward direction.

Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.

At time

t = 0

, terminal A in the circuit shown in the figure is connected to B by a key and an alternating current I

(t) = I

0 cos ($$\omega$$t), with I0 = 1 A and

\omega

= 500 rad s-1 starts flowing in it with the initial direction shown in the figure. At

t = {{7\pi } \over {6\omega }}

, the key is switched from B to D. Now onwards only A and D are connected. A total charge Q flows from the battery to charge the capacitor fully. If

C = 20

$$\mu$$F,

R = 10

\Omega

and the battery is ideal with emf of 50 V, identify the correct statement(s).
