is cut into lengths of ratio 
. They are connected in series and the new force constant is 
. If they are connected in parallel and force constant is 
, then 
is [NEET 2017]

Text Solution
Verified by ExpertsThe correct answer is:
C
When the spring is cut into pieces, they will have the new force constant. The spring is divided into 
ratio.
When the pieces are connected in series, the resultant force constant
In parallel, the net force constant,
The required ratio
