Two identical balls A and B each of mass 0.1 kg are attached to two identical mass less 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 0.06π m and force constant 0.1N/m. Initially both the balls are displaced by an angleθ = π / 6 radian with respect to the diameter PQ of the circle and released from rest. The frequency of oscillation of the ball B is

A. πHz

B. (1/π)Hz

C. 2πHz

D. (1/2π)Hz

E. None of the above

View Answer

Correct choice: B

Explanation:

As here two masses are connected by two springs, this problem is equivalent to the oscillation of a reduced mass of a spring of effective spring constant.
