Question

The graph shows the variation of displacement of a particle executing S.H.M. with time. We infer from this graph that

  1. The force is zero at time 3 T divided by 4    
  2. The velocity is maximum at time T divided by 2    
  3. The acceleration is maximum at time T    
  4. The P.E. is equal to total energy at time T divided by 2    

The correct answer is: The P.E. is equal to total energy at time T divided by 2


    At time fraction numerator T over denominator 2 end fraction semicolon   v equals 0 thereforeTotal energy = Potential energy

    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 theta equals pi divided by 6 radian with respect to the diameter P Q of the circle and released from rest.
