Two identical balls $A$ and $B$ each of mass $0.1 kg$ 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 the figure. The pipe is fixed in a horizontal plane. The centres of the balls can move in a circle of radius $0.06 m$. Each spring has a natural length of $0.06 \pi m$ and force constant $0.1 N / m$. Initially both the balls are displaced by an angle $\theta=\pi / 6$ radian with respect to the diameter $P Q$ of the circle and released from rest. The frequency of oscillation of the ball $B$ is
