    2. Relevant equations



    3. The attempt at a solution
    i have the solution , but in it , he assumes the center of mass is on the vertical and thus the distance of the vertical from the center is rsin(1/4∏)/(1/4∏) where r is the radius , so why did he take this assumption?

    The wire is freely suspended from point A.
    If the com was not vertically below point A, then what would happen?
