In the shown figure a conducting ring of mass m=2 kg and radius R=0.5 – InterviewSolution

1.	In the shown figure a conducting ring of mass m=2 kg and radius R=0.5 m lies on a smooth horizontal plane with its plane vertical. The ring carries a current of I=1πA. A horizontal uniform magnetic field of B=12 T is switched on at t=0. The initial angular acceleration α in rad/sec2 of the ring will be 4x,then x is
Answer» In the shown figure a conducting ring of mass $m = 2 kg$ and radius $R = 0.5 m$ lies on a smooth horizontal plane with its plane vertical. The ring carries a current of $I = \frac{1}{π} A$ . A horizontal uniform magnetic field of $B = 12 T$ is switched on at $t = 0$ . The initial angular acceleration $α$ in ${rad/sec}^{2}$ of the ring will be $4 x$ ,then $x$ is
