    Question

    The swing of a spinning cricket ball in air can be

    explained on the basis of –
    A Sudden change in wind direction. Correct Answer Incorrect Answer
    B Buoyancy of air. Correct Answer Incorrect Answer
    C Turbulence caused by wind. Correct Answer Incorrect Answer
    D Bernoulli's theorem. Correct Answer Incorrect Answer

    Solution

    The main theory of swing bowling surrounded turbulent and laminar airflow. Laminar air separates from the surface of the ball earlier than turbulent flow air, so that the separation point moves toward the front of the ball on the laminar side. On the turbulent flow side it remains towards the back; inducing a greater lift force on the turbulent airflow side of the ball.
