Question

A uniform chain of length 2L is hanging in equilibrium position, if end B is given a slightly downward displacement the imbalance causes an acceleration. Here pulley is small and smooth & string is inextensible The acceleration of end B when it has been displaced by distance x, is

  1. fraction numerator x over denominator L end fraction g    
  2. fraction numerator 2 x over denominator L end fraction g    
  3. fraction numerator x over denominator 2 end fraction g    
  4. g    

The correct answer is: fraction numerator x over denominator L end fraction g
