Question

15 There is a uniform rod of mass m and lengthlhaving particles A of mass m and B of mass 3mattached at its end. The rod is hinged at a point sothat it can turn in a vertical plane about ahorizontal axis. Distance of hinge from particle A,so that angular acceleration of system is minimumwhen released from horizontal position is
