Ball A is attached to one end of a rigid massless rod, while an identical ball B is attached to the center of the rod, as shown in the figure. Each ball has a mass of m = 0.550 kg, and the length of each half of the rod is L = 0.390 m. This arrangement is held by the empty end and is whirled around in a horizontal circle at a constant rate, so that each ball is in.uniform circular motion. Ball A travels at a constant speed of VA = 4.90 m/s. Find (a) the tension of the part between A and B of the rod and (b) the tension of the part between B and the empty end.
