A small block slides down on a smooth inclined plane, starting from rest at time $\displaystyle \mathrm{t}=0$. Let $\displaystyle \mathrm{S}_{\mathrm{n}}$ be the distance travelled by the block in the interval $\displaystyle \mathrm{t}=\mathrm{n}-1$ to $\displaystyle \mathrm{t}=\mathrm{n}$. Then, the ratio $\displaystyle \frac{\mathrm{S}_{\mathrm{n}}}{\mathrm{S}_{\mathrm{n}+1}}$ is :
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle \frac{2 \mathrm{n}-1}{2 \mathrm{n}+1}$
