Question

Two identical springs are attached at the opposite ends of a rod having length l and mass m. The rod could rotate about its mid-point O as shown in figure. Now, if the point A of the rod is pressed slightly and released, the rod starts executing oscillatory motion. The periodic time of this motion is………

  1. 2 pi square root of fraction numerator m over denominator 2 k end fraction end root    
  2. 2 pi square root of fraction numerator 2 m over denominator k end fraction end root    
  3. square root of fraction numerator 2 m over denominator 3 k end fraction end root    
  4. pi square root of fraction numerator 3 m over denominator 2 k end fraction end root    

The correct answer is: square root of fraction numerator 2 m over denominator 3 k end fraction end root
