A metal rod of length $L$ and mass $m$ is pivoted at one end. A thin disk of mass $M$ and radius $R left parenthesis less than L right parenthesis$ is attached at its centre to the free end of the rod. Consider two ways the disc is attached case $A$ - the disc is not free to rotate about its centre and case $B$ – the disc is free to rotate about its centre. The rod-disc system performs SHM in vertical plane after being released from the same displaced position. Which of the following statement(s) is/are true?

Two identical balls $A$ and $B$ each of mass $0.1 blank k g$ 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 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 $0.06 blank m.$ Each spring has a natural length of $0.06 pi blank m$ and force constant $0.1 N divided by m.$ Initially both the balls are displaced by an angle $theta equals pi divided by 6$ radian with respect to the diameter $P Q$ of the circle and released from rest. The frequency of oscillation of the ball $B$ is
