8. uniform disc radius of 0.2 m and a weight of 5 kg is rotated about an axis passing through its center and perpendicular to its plane. The dependence of the rate of disk rotation angle from the time given by the equation ω = A + Bt, where B = 8 rad / c2. Find tangential force applied to the rim of the disc. Friction neglected.
