A spring whose instretched length is `l` has a force constant `k`. The spring is cut into two pieces of unstretched lengths `l_(1)` and `l_(2)` where, `l_(1) =nl_(2)` and `n` is an integer. The ratio `k_(1)//k_(2)` of the corresponding force constant, `k_(1)` and `k_(2)` will be :

A

`(kn)/(n+1)`

B

`(k(n+1))/n`

C

`(k(n-1))/n`

D

`(kn)/(n-1)`
