A graph of force F against extension x is a straight line through the origin with gradient 250 N/m. The conclusion and constant are:

  1. F propto x with k = 0.004 N/m
  2. F propto x with spring constant 250 N/m
  3. F independent of x
  4. F propto x^2 with k = 250
Answer

B) F propto x with spring constant 250 N/m
