65. A disk with a radius R = 5 cm carries a charge uniformly distributed over the surface (σ = 80 nC / m2). Determine the magnetic moment pm due to the rotation of the disk about the axis passing through its center and perpendicular to the plane of the disk. Angular speed of disk rotation ω = 50 rad/s.
