Consider the three situations shown below. In each case two small carts are connected by a spring. A constant force F is applied to the leftmost cart in each case. In each situation the springs are compressed so that the distance between the two carts never changes.

Which of the following statements must be true regarding the compression of the spring in each case? Assume the springs are identical.

  1. Compression A = Compression B = Compression C
  2. B = C < A
  3. A < B = C
  4. A < B < C
  5. B < A < C
  6. C < A < B
  7. A < C < B
  8. None of the above
  9. Cannot be determined
