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

Options:

Answer:

Solution:

Here, $s_{n} = \frac{1}{n} a n^{2}$

$s_{n t h}$ = distance travelled in $n$ second - distance travelled in $(n - 1)$ second

$= (\frac{2 n - 1}{2}) a$

$∴ \frac{s_{n t h}}{s_{n}} = \frac{2 n - 1}{n^{2}} = \frac{2}{n} - \frac{1}{n^{2}}$
