Question
Two identical discs of same radius $R$ are rotating about their axes in opposite directions with the same constant angular speed $\omega$. The disc 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 function of times best represented by
