    1. The problem statement, all variables and given/known data

    From a uniform circular disc of radius 2 centimeter( its centre of mass is at 'O') , a circular portion of radius 1 cm is removed such that shift in centre of mass is maximum.The disc is now rotated about about 'O' perpendicular to the plane through an angle then the magnitude of displacement of new centre of mass is 1/square root of 3 centimeter. Then the angle of shifting is how much ?

    Answer given as 120 degree.

    2. Relevant equations



    3. The attempt at a solution
