A nonconducting ring of radius of 11.6 cm is uniformly charged with a total positive charge of 10.0 µC. The ring rotates at a constant angular speed 18.6 rad/s about an axis through its center, perpendicular to the plane of the ring. What is the magnitude of the magnetic field on the axis of the ring 5.00 cm from its center?
