An insulating circular ring of radius b lies in the xy plane, centered at the origin. It carries a linear charge density λ(φ) = λ0 sin φ, where λ0 is a constant and φ is the usual azimuthal angle. The ring is now set spinning at a constant angular velocity ω around the z axis. Calculate the power radiated.
