A metal disk with a radius of 22 cm rotates with a frequency of 60 rev/s. A magnetic field of 7 T is perpendicular to the disk. A resistor of 70 12 is connected between the center and the edge of the disk. How much current will run through the resistor? Answer in units of A. What torque is required to keep the disk spinning at the same rate? Answer in units of N middot m.
