Question

If masses are released from the position shown in figure then time elapsed before mass m1 collides with the floor will be :

  1. square root of fraction numerator 2 m subscript 1 end subscript g d over denominator m subscript 1 end subscript plus m subscript 2 end subscript end fraction end root    
  2. square root of fraction numerator 2 open parentheses m subscript 1 end subscript plus m subscript 2 end subscript close parentheses d over denominator open parentheses m subscript 1 end subscript minus m subscript 2 end subscript close parentheses g end fraction end root    
  3. square root of fraction numerator 2 open parentheses m subscript 1 end subscript minus m subscript 2 end subscript close parentheses d over denominator open parentheses m subscript 1 end subscript plus m subscript 2 end subscript close parentheses g end fraction end root    
  4. None of these    

The correct answer is: square root of fraction numerator 2 open parentheses m subscript 1 end subscript plus m subscript 2 end subscript close parentheses d over denominator open parentheses m subscript 1 end subscript minus m subscript 2 end subscript close parentheses g end fraction end root
