Q. A spring of force constant k is cut into three equal parts and then they are suspended from the same point. The force constant of the system is:

JIPMERJIPMER 2000

Solution:

We know that when a spring is cut into three equal parts, then the force constant of each part is 3k. Now these are suspended from the same point as a result of this these are connected in parallel. Hence $ {{k}_{\text{parallel}}}=3k+3k+3k=9k $
