Question
Three masses 700g, 500g, and 400g are suspended at the end of a spring a shown and are in equilibrium. When the 700g mass is removed, the system oscillates with a period of 3 seconds, when the 500 gm mass is also removed, it will oscillate with a period of
- 1 s
- 2 s
- 3 s
The correct answer is: 2 s
When mass 700 gm is removed, the left out mass (500 + 400) gm oscillates with a period of 3 sec
\ 
…...(i)
When 500 gm mass is also removed, the left out mass is 400 gm.

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 0.06p m and force constant 0.1N/m. Initially both the balls are displaced by an angle 
radian with respect to the diameter 
of the circle and released from rest. The frequency of oscillation of the ball B is
