alleryA spring of force constant k is cut into two equal halves. Spring constant of each half:
Ak²
Bk
C2k
Dk/2
Answer & Solution
Correct answer: C. 2k
Spring constant is inversely proportional to length.
**Cutting into half:** k_half = 2k.
So each half is stiffer (shorter springs are stiffer).
Two halves in series give back original k.
