Question

A particle is dropped vertically from rest from a height. The time taken by it to fall through successive distance of 1 m each will then be :

  1. All equal, being equal to square root of 2 divided by g end root second    
  2. In the ratio of the square roots of the integers 1, 2, 3.....    
  3. In the ratio of the difference in the square roots of the integers i.e. square root of 1 comma left parenthesis square root of 2 minus square root of 1 right parenthesis,left parenthesis square root of 3 minus square root of 2 right parenthesis comma left parenthesis square root of 4 minus square root of 3 right parenthesis……    
  4. In the ratio of the reciprocal of the square roots of the integers i.e.,. fraction numerator 1 over denominator square root of 1 end fraction comma fraction numerator 1 over denominator square root of 2 end fraction comma fraction numerator 1 over denominator square root of 3 end fraction comma fraction numerator 1 over denominator square root of 4 end fraction    

The correct answer is: In the ratio of the difference in the square roots of the integers i.e. square root of 1 comma left parenthesis square root of 2 minus square root of 1 right parenthesis,left parenthesis square root of 3 minus square root of 2 right parenthesis comma left parenthesis square root of 4 minus square root of 3 right parenthesis……
