Two identical discs of same radius R are rotating about their axes in opposite directions with the same constant angular speed `omega`. The discs are in the same horizontal plane. At time t-0, the points P and Q are facing each other as shown in the figure. The relative speed between the two points P and Q is `v_r`, As a function of time, it is best represented by
