A spring of force constant 
is cut into lengths of ratio 1:2: 3. They are connected in series and the new force constant is 
. Then they are connected in parallel and force constant is 
Then 
: 
is
Text Solution
Verified by ExpertsThe correct answer is:
B
Let us assume, the length of spring be l When we cut the spring into ratio oflength 1: 2: 3, we get three springs of lengths 
and 
with force constant,
When connected in series,
When connected in parallel,
