Two point-like beads of mass 8 are free to slide on a rod (mL2) of length L= 11 m and mass m as shown in the figure. Initially the beads are at the center and the rod is spinning freely (with no external torque) at w rad/s about a vertical axis through its center. Slowly the beads move radially out. At some instant, the angular speed of the system is and one of the bead is at distance 3 2L from the center. At this instant, what is the 5 distance of the other bead from the center (in m)? L
