Question

A ball of mass m is connected to two rubber bands of length L each, under tension T as shown in the figure. The entire system is placed on a smooth horizontal surface. the ball is displaced by a small distance y perpendicular to the length of the rubber bands. Assuming that tension in rubber bands doesn't change the angular frequency of oscillations performed by the ball is

  1. square root of fraction numerator T over denominator m L end fraction end root    
  2. square root of fraction numerator 2 text end text T over denominator text end text m L end fraction end root    
  3. square root of fraction numerator T over denominator 2 text end text m L end fraction end root    
  4. square root of fraction numerator m L over denominator 2 text end text T end fraction end root    

The correct answer is: square root of fraction numerator 2 text end text T over denominator text end text m L end fraction end root
