A body starts from rest and moves with a constant acceleration. The ratio of distance covered in the n th second to the distance covered in n second is

Step-by-step solution

Here, s n = 1 n a n 2 s n t h = distance travelled in n second - distance travelled in ( n - 1 ) second = 2 n - 1 2 a ∴ s n t h s n = 2 n - 1 n 2 = 2 n - 1 n 2
