Hook's law states that the amount of deformation produced by a for is proportional to the amount of force. If you put 1-pound weight on a spring cause the spring to stretch 0.75 in. A 2-pound weight will cause a deformation of 1.5. In equation form we can werite:

F = k • x

F - is the force applied
k - is a constant (called the spring constant)
x - is the deformation

What is value of k?

Answer = (1)
