Rotational MotionHard
Question
Two identical discs of same radius R are rotating about their axes inopposite directions with the same constant angular speed ω Thediscs are in the same horizontal plane. At time t = 0, the points Pand Q are facing each other as shown in the figure. The relativespeed between the two points P and Q is vr. In one time period (T)of rotation of the discs, vr as a function of time is best representedby
Options
A.
B.
C.
D.
Solution
In each rotation relative speed becomes zero twice and becomes maximum twice.
