Four identical springs each have the same spring constant k.If these four springs are attached end to end forming a spring four times the length of one of the original springs,what will be the spring constant of the combination?
A) k
B) k/4
C) 4k
D) 1.41k

When springs are attached end to end (in series), the overall spring constant of the combination is reduced. The formula for the equivalent spring constant k_eq of n identical springs in series is k_eq = k/n. Here, n = 4, so the spring constant of the combination is k/4.
