An insulating uniformly charged cylindrical shell of radius a lies with its axis along the z axis The shell s moment of inertia per unit length about the z axis and the surface charge density are I and a respectively The cylinder is placed in an external uniform magnetic field Bex z and is initially at rest Starting at t 0 the external magnetic field is slowly reduced to zero What is the final angular velocity w of the cylinder 0 2a Bex 2
