If the given spring of spring constant K is cut into three identical segments the sum of spring constant of each segment:
Correct answer: D. 3K
- A. 1K
- B. K/2
- C. K/3
- D. 3K
- E. 4K
Explanation
When a spring is cut into segments, the spring constant of each segment remains the same. Therefore, if the original spring has a spring constant K, each segment will also have a spring constant of K. So the summation will be 3K. Therefore option D is the correct option.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
