In the figure shown, there is a magnetic field in the x - direction with |B| = 0.2 T , The loop has an area of 5 `cm^(2)` and rotates about line CD as z - axis. Point A rotates towards positvie x axis and intially x - axis is perpanedicular to the plane of the loop. If AE rotates through an angle of `30^(@)` from the intial position in 0.2 seconds.
