Distances covered in successive equal time intervals by a body falling from rest are in what ratio?
A1 : 3 : 5 : 7
B1 : 2 : 3 : 4
C1 : 4 : 9 : 16
D1 : 2 : 4 : 8
Answer & Solution
Correct answer: A. 1 : 3 : 5 : 7
Distance in the nth interval goes as 2n - 1, giving the odd number ratio 1 : 3 : 5 : 7.
