Question

A uniform cylinder of mass m can rotate freely about its own axis which is horizontal. A particle of mass mo hangs from the end of a light string wound round the cylinder which does not slip over it. When the system is allowed to move, the acceleration of the descending mass will be

  1. fraction numerator 2 m subscript o end subscript g over denominator m plus 2 m subscript o end subscript end fraction    
  2. fraction numerator m subscript o end subscript g over denominator m plus m subscript o end subscript end fraction    
  3. fraction numerator 2 m subscript 0 end subscript g over denominator m plus m subscript o end subscript end fraction    
  4. fraction numerator m subscript o end subscript g over denominator 2 m plus m subscript o end subscript end fraction    

The correct answer is: fraction numerator 2 m subscript o end subscript g over denominator m plus 2 m subscript o end subscript end fraction
