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.
