When a spring is cut into shorter lengths, the spring constant of each shorter spring increases. For a spring cut into n equal parts, the spring constant of each part becomes n times the original spring constant. Therefore, if the spring is cut into 4 equal lengths, the spring constant of each shorter spring is 4k.
