    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 equals 0, the points P and Q are facing each other as shown in figure. The relative speed between the two points P and Q is V subscript r end subscript as function of times best represented by


    So, V subscript r end subscript equals 2 omega R sin invisible function application left parenthesis omega t right parenthesis
    At t equals T divided by 2 comma blank V subscript r end subscript equals 0
    So two half cycles will take place

    The figure shows a circular path of a moving particle. If the velocity of the particle at same instant is v equals negative 3 stack stack i with dot on top with hat on top minus 4 stack stack j with dot on top with hat on top, through which quadrant is the particle moving when clockwise and anti-clockwise respectively

    The figure shows a circular path of moving particle. At any instant velocity of particle.

    v equals negative 3 stack stack i with dot on top with hat on top minus 4 stack stack j with dot on top with hat on top equals left parenthesis negative 3 comma negative 4 right parenthesis (In coordinate from).
    The coordinates of velocity show that particle is in 3rd quadrant at that instant. While moving clockwise particle will enter into 4th quadrant and these into 3rd and while moving anticlockwise particle will enter into 2nd quadrant and then into 3rd quadrant.
