Distance travelled by disc B in one complete revolution around disc A is equal to the circumference of the disc A
Therefore
Distance travelled = 2 πR
For 2 straight pi radians distance covered by disc B is 4 πR
Therefore for 2 πR length travelled 
Angle should be fraction numerator 2 πR over denominator 4 πR end fraction cross times 2 straight pi equals straight pi

At t=0 a bead of mass m is placed at a distance \frac{L}{2} from the axis of rotation. Initial speed of the bead is zero with respect to the rod. The rod is rotated with a constant angular velocity o as shown in diagram. Find the velocity of bead w.r.t ground, when it leaves out of the rod. (Given L is the length of rod.)
