Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. k
  2. k/2
  3. 2k
  4. 4k

Correct answer and explanation

Correct answer: 2k

Explanation: āœ… Correct Answer: C. 2k šŸ“š Explanation: The spring constant (k) is inversely proportional to the length of the spring. When a spring is cut into two equal halves, the length of each new spring becomes half of the original length. Therefore, the spring constant of each half will double. Calculation: 1 divided by (1/2) equals 2. So, the new spring constant for each piece is exactly '2k'.
