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
