A particle starts sliding down a frictionless inclined plane. If ` S_(n) ` is the distance travelled by it from time ` t = n-1 sec `, to `t = n sec`, the ratio ` (S_(n))/(s_(n+1))` is

A

`(2n-1)/(2n)`

B

`(2n+1)/(2n-1)`

C

`(2n-1)/(2n+1)`

D

`(2n)/(2n+1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`S_(n)=u+a/2(2n-1)=a/2 (2n-1)`
`S_((n+1))=x+a/2 (2n+1)=a/2 (2n+1)`
`rArr S_(n)/S_(n+1)=((2n-1))/((2n+1))`
