A flat surface of a thin uniform disk A of radius R is glued to a horizontal table. Another thin uniform disk B of mass M and with the same radius R rolls without slipping on the circumference of A , as shown in the figure. A flat surface of B also lies on the plane of the table. The center of mass of B has fixed angular speed co about the vertical axis passing through the center of A . The angular momentum of B is nMcoR 2 with respect to the center of A . Which of the following is the value of n ? 9/2
