Thee force constant can be obtained using the relation, K = F/e
What is Hooke's law?
According to Hooke's law, as long as the elastic limit is not exceeded, the extension is directly proportional to the force applied. In this case, the question is incomplete since the force applied is missing.
Now, from Hooke's law;
F = Ke
K = F/e
Hence, if we have the force applied, we can conveniently obtain the force constant of the spring.
