A line charge A 106 c m is fixed on the rim of a wheel of radius R 1m which is then suspended horizontally so that it is free to rotate the 1 17 pointing up Now suddenly the m there is uniform magnetic field Bo spokes are made of wood In the central region up to radius a field is turned off If the moment of inertia is l 0 25 kg m the final angular velocity w of the wheel is nx 10 rad s Find n a R C
