The ratios of the distances traversed, in successive intervals of time by a body, falling from rest are

  1. 1 blank colon 3 blank colon 5 blank colon 7 blank colon 9 blank colon  
  2. 2 blank colon 4 blank colon 6 blank colon 8 blank colon 10 blank colon  
  3. 1 blank colon 4 blank colon 7 blank colon 10 blank colon 13 blank colon  
  4. None of theses  

The correct answer is: 1 blank colon 3 blank colon 5 blank colon 7 blank colon 9 blank colon


    Here, u equals 0 comma blank a equals g
    Distance travelled in n to the power of t h end exponent second is given by
    D subscript n end subscript equals u plus fraction numerator a over denominator 2 end fraction open parentheses 2 n minus 1 close parentheses blank therefore D subscript n end subscript proportional to left parenthesis 2 n minus 1 right parenthesis
    therefore D subscript 1 end subscript colon D subscript 2 end subscript colon D subscript 3 end subscript blank colon D subscript 4 end subscript blank colon D subscript 5 end subscript equals 1 blank colon 3 blank colon 5 blank colon 7 blank colon 9 blank colon
