Question
One end of a spring of force constant k is fixed to a vertical wall and the other to a block of mass m resting on a smooth horizontal surface. There is another wall at a distance 
from the black. The spring is then compressed by 
and released. The time taken to strike the wall is
The correct answer is:
The total time from A to C
where T = time period of oscillation of spring mass system
can be obtained from, 
Putting 
we obtain 
Þ 
.

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
