Question 37

A student wishes to determine the spring constant of a spring where it obeys Hooke's law. Different loads are hung from the spring and its total length is measured. When the load is 0 N, the length of the spring is 15 cm. When the load is 3.0 N, the length is 21 cm. When the load is 6.0 N, the length is 27 cm. When the load is 8.0 N, the length is 35 cm. What is the value of the spring constant of the spring in the range where it obeys Hooke's law?

A

0.14 N/cm0.14\text{ N/cm}0.14 N/cm

B
