Two identical balls A and B of mass m kg are attached to two identical massless springs. The spring mass system is constrained to move inside a rigid smooth pipe bent in the form of a circle as shown in figure. The pipe is fixed in a horizontal plane. The centres of the balls can move in a circle of radius r metre. Each spring has a natural length of   metre and spring constant K. Initially, both the balls are displaced by an angle  radian w.r.t. diameter PQ of the circles and released from rest. The speed of ball A when A and B are at the two ends of dia PQ is
